Program:

 public class HexadecimalIntegerLiteral {

  public static void main(String[] a) {
    int hexValue1 = 0x100;
    int hexValue2 = 0x1234;
    int hexValue3 = 0xDEAF;
    int hexValue4 = 0xCAB;

    System.out.println(hexValue1);
    System.out.println(hexValue2);
    System.out.println(hexValue3);
    System.out.println(hexValue4);
  }

}

/* Put 0x or 0X in front of the numbers.
Use the letters A to F (or a to f) to represent digits
with values 10 to 15, respectively.  */

Output:

256
4660
57007
3243

Explanation:

This is a Java program that demonstrates the use of hexadecimal integer literals. In Java, an integer literal is a sequence of digits that represents a whole number value. A hexadecimal integer literal is a special type of integer literal that represents a value in base 16, using the digits 0-9 and the letters A-F.

The program declares four integer variables, named hexValue1, hexValue2, hexValue3, and hexValue4, and assigns them different hexadecimal integer literals as values. Specifically:

  • hexValue1 is assigned the value 0x100, which represents the decimal value 256.
  • hexValue2 is assigned the value 0x1234, which represents the decimal value 4660.
  • hexValue3 is assigned the value 0xDEAF, which represents the decimal value 57007.
  • hexValue4 is assigned the value 0xCAB, which represents the decimal value 3243.

The program then prints the values of these variables to the console using the System.out.println method. When run, the program will output the decimal values of the four hexadecimal integer literals, which are 256, 4660, 57007, and 3243, respectively.
