Find ASCII value of a character - Java Program

import java.util.Scanner;
 
public class ASCIIValue {
    public static void main(String[] args) {
 
        Scanner sc = new Scanner(System.in);
 
        // Taking character input from user
        System.out.print("Enter any character: ");
        char ch = sc.next().charAt(0);
 
        // Typecasting char to int gives ASCII value
        int ascii = (int) ch;
 
        // Displaying ASCII value
        System.out.println("The ASCII value of '" + ch + "' is: " + ascii);
 
        sc.close();
    }
}
 

 
OUTPUT 1:
Enter any character: A
The ASCII value of 'A' is: 65

OUTPUT 2:
Enter any character: z
The ASCII value of 'z' is: 122

Explanation

Step 1 — Take a Character as Input

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

• next() reads a string
• charAt(0) extracts the first character
• We store it in a char variable ch

Step 2 — Convert char to int

int ascii = (int) ch;

• A character in Java internally represents a Unicode value
• Casting it to int gives its ASCII (same for standard characters A–Z, a–z, 0–9, symbols)

Step 3 — Print the ASCII Value

System.out.println("The ASCII value of '" + ch + "' is: " + ascii);
