Program/Source Code:

The source code to demonstrate an example of the left shift (<<) operator is given below. The given program is compiled and executed successfully.

// Java program to demonstrate an example 
// of left shift (<<) operator

public class Main {
  public static void main(String[] args) {
    int num = 0xff;

    System.out.printf("Number before left shift: %04X\n", num);

    //shifting 2 bits left
    num = (num << 2);

    System.out.printf("Number after left shift: %04X\n", num);
  }
}

Output:

Number before left shift: 00FF
Number after left shift: 03FC

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 created an integer variable initialized with 0xff. Then we performed left-shift operation and printed the result.

Binary of 0xFF in (in bytes format) - 0000 0000 1111 1111.

After 2 bits left shift (in bytes format) – 0000 0011 1111 1100, which is equivalent of 0x03FC.
