Java Program to Print Character ASCII Value

Last Updated: 14 March, 2023

On this tutorial page we are going to learn how to write a Java program to print ASCII value of each character.

ASCII (American Standard Code for Information Interchange) is a character encoding standard used to represent text in computers. Each character in the ASCII table is assigned a unique code or value between 0 and 127, including uppercase and lowercase letters, digits, punctuation marks, and special characters.

Here's a Java program to find the ASCII value of a given character:

Example 1 :

  public class AsciiValuee {
    public static void main(String[] args) {
      char ch = 's';
          int asciiValue = ch;
          
          // ASCII value will be assigned if we cast char into int
          int castAsciiValue = (int) ch;
  
          System.out.println("The ASCII value of " + ch + " is: " + asciiValue);
          System.out.println("The ASCII value of " + ch + " is: " + castAsciiValue);
  
    }
  }

Output

The ASCII value of s is: 115
The ASCII value of s is: 115

Example 2 :

  public class AsciiValuee2 {
    public static void main(String[] args) {
      Scanner scanner = new Scanner(System.in);
      System.out.print("Enter the character: ");
      char ch = scanner.next().charAt(0);
          int asciiValue = ch;
          scanner.close();
          
          // ASCII value will be assigned if we cast char into int
          int castAsciiValue = (int) ch;
  
          System.out.println("The ASCII value of " + ch + " is: " + asciiValue);
          System.out.println("The ASCII value of " + ch + " is: " + castAsciiValue);
  
    }
  }

Output

Enter the character: G
The ASCII value of G is: 71
The ASCII value of G is: 71

Example 3 :

  public class AsciiValuee3 {
    public static void main(String[] args) {
  
      String str = "SMILE";
      System.out.println("String: " + str + "\n");
      // Array for storing ASCII value of each character
      int[] asciiArr = new int[str.length()];
  
      // Character to ASCII value
      for (int i = 0; i < str.length(); i++) {
        System.out.println("Character: " + str.charAt(i) + " - ASCII value: " + (int) str.charAt(i));
        asciiArr[i] = (int) str.charAt(i);
      }
  
      System.out.println(); 	// New Line
      
      // Reverse Operation: ASCII value to Character
      for (int i = 0; i < str.length(); i++) {
        System.out.println("ASCII Value: " + asciiArr[i] + " Character: " + (char)asciiArr[i]);
      }
    }
  }

Output

String: SMILE

Character: S - ASCII value: 83
Character: M - ASCII value: 77
Character: I - ASCII value: 73
Character: L - ASCII value: 76
Character: E - ASCII value: 69

ASCII Value: 83 Character: S
ASCII Value: 77 Character: M
ASCII Value: 73 Character: I
ASCII Value: 76 Character: L
ASCII Value: 69 Character: E
