Fundamental Concepts of Java MultiThreading

What is a Thread?

A thread is the smallest unit of execution within a process. In Java, a thread is an instance of the Thread class or a class that implements the Runnable interface. Each thread has its own call stack, program counter, and local variables, allowing it to execute independently of other threads.

Thread States

Java threads can be in one of the following states:

  • New: The thread is created but not yet started.
  • Runnable: The thread is ready to run and is waiting for the CPU to allocate time.
  • Blocked: The thread is waiting for a monitor lock to enter a synchronized block or method.
  • Waiting: The thread is waiting indefinitely for another thread to perform a particular action.
  • Timed Waiting: The thread is waiting for a specified amount of time.
  • Terminated: The thread has completed its execution.

Concurrency vs. Parallelism

  • Concurrency: Concurrency refers to the ability of a program to handle multiple tasks at the same time. In a single - core system, the CPU switches between different threads rapidly, giving the illusion of simultaneous execution.
  • Parallelism: Parallelism means that multiple tasks are actually executed simultaneously on multiple CPU cores.

Basic Usage of Java MultiThreading API

Creating Threads

There are two common ways to create threads in Java:

  1. Extending the Thread class:
class MyThread extends Thread {
    @Override
    public void run() {
        System.out.println("Thread is running.");
    }
}

public class BasicThreadExample {
    public static void main(String[] args) {
        MyThread thread = new MyThread();
        thread.start();
    }
}
  1. Implementing the Runnable interface:
class MyRunnable implements Runnable {
    @Override
    public void run() {
        System.out.println("Runnable is running.");
    }
}

public class RunnableExample {
    public static void main(String[] args) {
        MyRunnable runnable = new MyRunnable();
        Thread thread = new Thread(runnable);
        thread.start();
    }
}

Starting and Stopping Threads

To start a thread, you call the start() method. Once a thread has completed its execution, it enters the terminated state and cannot be restarted. In the past, the stop() method was used to stop a thread, but it is now deprecated because it can leave the program in an inconsistent state. A better way to stop a thread is by using a flag:

class StoppableThread extends Thread {
    private volatile boolean isStopped = false;

    @Override
    public void run() {
        while (!isStopped) {
            System.out.println("Thread is running...");
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
        System.out.println("Thread is stopped.");
    }

    public void stopThread() {
        this.isStopped = true;
    }
}

public class StopThreadExample {
    public static void main(String[] args) {
        StoppableThread thread = new StoppableThread();
        thread.start();
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
        thread.stopThread();
    }
}

Synchronization Basics

Synchronization is used to ensure that only one thread can access a shared resource at a time. You can use the synchronized keyword to achieve this:

class Counter {
    private int count = 0;

    public synchronized void increment() {
        count++;
    }

    public int getCount() {
        return count;
    }
}

public class SynchronizationExample {
    public static void main(String[] args) throws InterruptedException {
        Counter counter = new Counter();
        Thread t1 = new Thread(() -> {
            for (int i = 0; i < 1000; i++) {
                counter.increment();
            }
        });
        Thread t2 = new Thread(() -> {
            for (int i = 0; i < 1000; i++) {
                counter.increment();
            }
        });
        t1.start();
        t2.start();
        t1.join();
        t2.join();
        System.out.println("Final count: " + counter.getCount());
    }
}

Common Practices in Java MultiThreading

Thread Pools

Thread pools are a collection of pre - created threads that can be reused to execute tasks. Java provides the ExecutorService interface and its implementations to manage thread pools:

import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;

public class ThreadPoolExample {
    public static void main(String[] args) {
        ExecutorService executor = Executors.newFixedThreadPool(2);
        for (int i = 0; i < 5; i++) {
            final int taskNumber = i;
            executor.submit(() -> {
                System.out.println("Task " + taskNumber + " is being executed by " + Thread.currentThread().getName());
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
                System.out.println("Task " + taskNumber + " is completed.");
            });
        }
        executor.shutdown();
    }
}

Callable and Future

The Callable interface is similar to Runnable, but it can return a result. The Future interface is used to retrieve the result of a Callable task:

import java.util.concurrent.*;

class MyCallable implements Callable<Integer> {
    @Override
    public Integer call() throws Exception {
        Thread.sleep(2000);
        return 10;
    }
}

public class CallableFutureExample {
    public static void main(String[] args) throws ExecutionException, InterruptedException {
        ExecutorService executor = Executors.newSingleThreadExecutor();
        MyCallable callable = new MyCallable();
        Future<Integer> future = executor.submit(callable);
        System.out.println("Waiting for the result...");
        Integer result = future.get();
        System.out.println("Result: " + result);
        executor.shutdown();
    }
}

Producer - Consumer Pattern

The producer - consumer pattern is a classic multi - threading pattern where one or more producer threads generate data and one or more consumer threads consume the data. A BlockingQueue can be used to implement this pattern:

import java.util.concurrent.BlockingQueue;
import java.util.concurrent.LinkedBlockingQueue;

class Producer implements Runnable {
    private BlockingQueue<Integer> queue;

    public Producer(BlockingQueue<Integer> queue) {
        this.queue = queue;
    }

    @Override
    public void run() {
        for (int i = 0; i < 5; i++) {
            try {
                queue.put(i);
                System.out.println("Produced: " + i);
                Thread.sleep(100);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

class Consumer implements Runnable {
    private BlockingQueue<Integer> queue;

    public Consumer(BlockingQueue<Integer> queue) {
        this.queue = queue;
    }

    @Override
    public void run() {
        try {
            while (true) {
                Integer item = queue.take();
                System.out.println("Consumed: " + item);
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

public class ProducerConsumerExample {
    public static void main(String[] args) {
        BlockingQueue<Integer> queue = new LinkedBlockingQueue<>();
        Thread producerThread = new Thread(new Producer(queue));
        Thread consumerThread = new Thread(new Consumer(queue));
        producerThread.start();
        consumerThread.start();
    }
}

Advanced Java MultiThreading Techniques

Fork/Join Framework

The Fork/Join framework is designed for parallelizing recursive algorithms. It divides a large task into smaller subtasks and then combines the results of the subtasks:

import java.util.concurrent.ForkJoinPool;
import java.util.concurrent.RecursiveTask;

class SumTask extends RecursiveTask<Integer> {
    private static final int THRESHOLD = 10;
    private int[] array;
    private int start;
    private int end;

    public SumTask(int[] array, int start, int end) {
        this.array = array;
        this.start = start;
        this.end = end;
    }

    @Override
    protected Integer compute() {
        if (end - start <= THRESHOLD) {
            int sum = 0;
            for (int i = start; i < end; i++) {
                sum += array[i];
            }
            return sum;
        } else {
            int mid = (start + end) / 2;
            SumTask leftTask = new SumTask(array, start, mid);
            SumTask rightTask = new SumTask(array, mid, end);
            leftTask.fork();
            int rightResult = rightTask.compute();
            int leftResult = leftTask.join();
            return leftResult + rightResult;
        }
    }
}

public class ForkJoinExample {
    public static void main(String[] args) {
        int[] array = new int[100];
        for (int i = 0; i < 100; i++) {
            array[i] = i;
        }
        ForkJoinPool pool = new ForkJoinPool();
        SumTask task = new SumTask(array, 0, array.length);
        int result = pool.invoke(task);
        System.out.println("Sum: " + result);
    }
}

ReentrantLock and Condition

ReentrantLock is a more flexible alternative to the synchronized keyword. Condition is used in conjunction with ReentrantLock to implement more complex waiting and signaling mechanisms:

import java.util.concurrent.locks.Condition;
import java.util.concurrent.locks.ReentrantLock;

class Buffer {
    private final ReentrantLock lock = new ReentrantLock();
    private final Condition notFull = lock.newCondition();
    private final Condition notEmpty = lock.newCondition();
    private int[] buffer;
    private int count = 0;
    private int in = 0;
    private int out = 0;

    public Buffer(int size) {
        this.buffer = new int[size];
    }

    public void put(int item) throws InterruptedException {
        lock.lock();
        try {
            while (count == buffer.length) {
                notFull.await();
            }
            buffer[in] = item;
            in = (in + 1) % buffer.length;
            count++;
            notEmpty.signal();
        } finally {
            lock.unlock();
        }
    }

    public int take() throws InterruptedException {
        lock.lock();
        try {
            while (count == 0) {
                notEmpty.await();
            }
            int item = buffer[out];
            out = (out + 1) % buffer.length;
            count--;
            notFull.signal();
            return item;
        } finally {
            lock.unlock();
        }
    }
}

public class ReentrantLockExample {
    public static void main(String[] args) {
        Buffer buffer = new Buffer(5);
        // Producer and consumer threads can be added here similar to the producer - consumer example
    }
}

Atomic Variables

Atomic variables are used to perform atomic operations without using locks. Java provides classes like AtomicInteger, AtomicLong, etc.:

import java.util.concurrent.atomic.AtomicInteger;

public class AtomicVariableExample {
    public static void main(String[] args) throws InterruptedException {
        AtomicInteger atomicInt = new AtomicInteger(0);
        Thread t1 = new Thread(() -> {
            for (int i = 0; i < 1000; i++) {
                atomicInt.incrementAndGet();
            }
        });
        Thread t2 = new Thread(() -> {
            for (int i = 0; i < 1000; i++) {
                atomicInt.incrementAndGet();
            }
        });
        t1.start();
        t2.start();
        t1.join();
        t2.join();
        System.out.println("Final value: " + atomicInt.get());
    }
}

Best Practices in Java MultiThreading

Avoiding Deadlocks

Deadlocks occur when two or more threads are blocked forever, each waiting for the other to release a resource. To avoid deadlocks, you can follow these rules:

  • Acquire locks in a consistent order.
  • Use time - bound lock acquisitions.
  • Avoid nested locks.

Proper Resource Management

Make sure to release resources properly when a thread is done using them. For example, close files, database connections, etc. You can use try - with - resources statements or finally blocks to ensure resource release.

Testing and Debugging MultiThreaded Code

  • Use logging to track the execution flow of threads.
  • Use tools like VisualVM or YourKit to analyze thread performance and detect issues like deadlocks and resource leaks.
  • Write unit tests using frameworks like JUnit and Mockito to test multi - threaded code.

Conclusion

Java multi - threading is a powerful feature that can significantly improve the performance and responsiveness of applications. By understanding the fundamental concepts, basic usage, common practices, and advanced techniques of the Java multi - threading API, developers can write efficient and reliable multi - threaded code. However, multi - threading also introduces challenges such as deadlocks and race conditions, so it is important to follow best practices when developing multi - threaded applications.
