In this program, we will sleep program execution 4 specified milliseconds using Thread.Sleep() method.

Program/Source Code:

The source code to sleep program execution for specified milliseconds is given below. The given program is compiled and executed successfully.

// Java program to sleep program 
// for specified milliseconds

public class Main {
  public static void main(String[] args) {
    try {
      System.out.println("Hello");
      Thread.sleep(1000);
      System.out.println("Hii");
    } catch (Exception e) {
      System.out.println(e);
    }
  }
}

Output:

Hello
Hii

Explanation:

In the above program, we created a public class Main. It contains a static method main().

The main() method is an entry point for the program. Here, we printed the "Hello" message. Then we slept program execution for 1000 milliseconds. After that, we printed the "Hii" message.
