Find ASCII value of a Character in Java

Write a program in Java to find the ASCII value of a Character:

ASCII or American Standard Code for Information Interchange is a character encoding standard to represent characters in computers. By using a 7-bit binary number, a character is defined. There are 128 possible characters. In decimal form, we can represent a character from 0 to 127.

We have two different ways to find the ASCII value of a character in Java:

1. We can assign the character variable to an integer variable. Since an integer variable can’t hold a character variable, it will keep the ASCII value of the assigned character.

2. Typecast the character to an integer.

The below program shows both of these ways:

class Main {
    public static void main(String[] args) {
        char c = 'b';

        //1 : Assigning
        int value = c;
        System.out.println("Ascii : " + value);

        //2 : Typecasting
        System.out.println("Ascii : " + (int) c);
    }
}

Output :

Ascii : 98
Ascii : 98

The advantage of typecasting is that you don’t need to create another integer variable.

Example 2: How to find the ASCII value of any user-input character:

The following program takes one character as input and prints its ASCII:

import java.util.Scanner;

class Main {
    public static void main(String[] args) {
        try (Scanner sc = new Scanner(System.in)) {
            System.out.println("Enter a character: ");

            char c = sc.next().charAt(0);

            System.out.println("Ascii : "+(int)c);
        }

    }
}

The program is self-explanatory. If you run it, it will ask you to enter a character and print its ASCII.
