The source code to print the current date-time using the Calendar class is given below. The given program is compiled and executed successfully.

// Java program to print current date-time 
// using Calendar class

import java.util.*;

public class Main {
  public static void main(String[] args) {
    Calendar cal = Calendar.getInstance();

    System.out.println("The Current DateTime is: [" + cal.getTime() + "]");
  }
}

Output:

The Current DateTime is: [Fri Apr 01 06:58:17 GMT 2022]

Explanation:

In the above program, we created a class Main that contains a static method main(). The main() method is the entry point for the program, here we created the object of the Calendar class and get the current date-time using the getTime() method, and printed the result.
