Temporarily Stop a Thread in Java

In Java, sometimes a thread needs to pause its execution for a specific period of time before continuing its work. This can be done using the Thread.sleep() method, which temporarily suspends the current thread.

• The time is provided in milliseconds.
• It throws an InterruptedException, so it must be handled using try-catch.

Note: suspend() method is deprecated in the latest Java version.

Syntax:

public final void suspend()

Output

Explanation: Three threads (t1, t2, t3) are created and started, so they run concurrently and execute the run() method independently. Each thread prints its name and numbers 1–4 with a small delay, so the output appears interleaved and in random order due to multithreading.

Note: Thread t2 can be resumed by resume() method.
