Java program to print the ASCII value of an integer

import java.util.Scanner;

public class Main {

    /**
     * Utility functions
     */
    static void println(String string) {
        System.out.println(string);
    }

    static void print(String string) {
        System.out.print(string);
    }

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

        println("********** Java program to convert ASCII to Character **********");
        println("");

        int ascii;

        println("Enter a ASCII value within 0 to 127 :");

        //read the integer value
        ascii = sc.nextInt();

        if (ascii > 127) {
            println("Please enter a valid input !!");
        } else {
            //convert the integer value to character
            char asciiChar = (char) ascii;

            println("ASCII value of " + ascii + " is " + asciiChar);
        }
    }
}

Enter a ASCII value within 0 to 127 :
124
ASCII value of 124 is |

Enter a ASCII value within 0 to 127 :
82
ASCII value of 82 is R

Enter a ASCII value within 0 to 127 :
92
ASCII value of 92 is \

Enter a ASCII value within 0 to 127 :
120
ASCII value of 120 is x
