Submitted by Nidhi, on March 05, 2022

Problem statement

In this program, we will read a string from the user and print the input string in hexadecimal format using the "%X" format specifier in System.out.printf() method.

Source Code

The source code to print string in hexadecimal format is given below. The given program is compiled and executed successfully.

// Java program to print string in 
// hexadecimal format

import java.util.Scanner;

public class Main {
  public static void main(String[] args) {
    Scanner SC = new Scanner(System.in);

    String str;
    int i = 0;

    System.out.print("Enter string: ");
    str = SC.next();

    System.out.print("Hexadecimal string: ");

    for (i = 0; i < str.length(); i++) {
      System.out.printf("%02X ", (int) str.charAt(i));
    }

    System.out.println();
  }
}

Output

Enter string: www.includehelp.com
Hexadecimal string: 77 77 77 2E 69 6E 63 6C 75 64 65 68 65 6C 70 2E 63 6F 6D

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 read a string from the user using the Scanner class. Then we printed the hexadecimal value corresponding to each character of string using the System.out.printf() method on the console screen.
