In this program, we will extract bytes from an integer (Hexadecimal) value and print extracted bytes.

Program/Source Code:

The source code to extract bytes from an integer (Hex) value, is given below. The given program is compiled and executed successfully.

// Java program to extract bytes from 
// an integer (Hex) value

public class Main {
  public static void main(String[] args) {
    int value = 0x11223344; //4 Bytes value

    int a, b, c, d; //to store byte by byte value

    a = (value & 0xFF); //extract first byte
    b = ((value >> 8) & 0xFF); //extract second byte
    c = ((value >> 16) & 0xFF); //extract third byte
    d = ((value >> 24) & 0xFF); //extract fourth byte

    System.out.printf("First Byte  = %02X\n", a);
    System.out.printf("Second Byte = %02X\n", b);
    System.out.printf("Third Byte  = %02X\n", c);
    System.out.printf("fourth Byte = %02X\n", d);
  }
}

Output:

First Byte  = 44
Second Byte = 33
Third Byte  = 22
fourth Byte = 11

Explanation:

In the above program, we imported the "java.util.Scanner" package to read input from the user. And, created a public class Main. It contains a static method main().

The main() method is an entry point for the program. Here, we extracted the bytes from an integer number and printed the result.
