Cap Programming with multiple threads

Main skills and concepts
• Understand the fundamentals of creating multiple threads
• Know the Thread class and the Runnable
interface • Create a thread
• Create multiple threads
• Determine when a thread ends
• Use thread priorities
• Understand thread synchronization
• Use synchronized methods
• Use synchronized blocks
• Promote communication between threads
• Suspend, resume and stop threads

Threads: These are independent paths of execution within a program.
Multitasking: It can be based on processes (several programs) or threads (several tasks in the same program).
Advantages:
Greater efficiency when using idle time.
Better use of multicore/multiprocessor systems.

Thread Creation and Management

Classes and Interfaces:
Thread: Class that encapsulates threads.
Runnable: Interface used to define custom threads.

Common Thread Class Methods:

• getName(): Returns the name of the thread.
• getPriority(): Returns the priority.
• isAlive(): Checks if the thread is still executing.
• join(): Waits for the thread to finish.
• run(): Defines the entry point of the thread.
• sleep(long ms): Suspends the thread for a period of time.
• start(): Starts thread execution.

Creating Threads:

• Implementing Runnable:

class MyThread implements Runnable {
    String threadName;

    MyThread(String name) {
        threadName = name;
    }

    public void run() {
        System.out.println(threadName + " starting.");
        try {
            for (int i = 0; i 


<p>Expected output:<br>
</p>

<pre class="brush:php;toolbar:false">Main thread starting.
.
Child #1 starting.
..
In Child #1, count is 0
...
In Child #1, count is 1
...
Main thread ending.

Thread Class Extension:

class MyThread extends Thread {
    MyThread(String name) {
        super(name);
    }

    public void run() {
        System.out.println(getName() + " starting.");
        try {
            for (int i = 0; i 



<p>note: The sleep() method makes the thread in which it is called suspend execution <br>
for the specified period of milliseconds.</p>
