Java Program to accept any String and display the ASCII Code of all characters in the String

The following Code is to get the ASCII Code (American Standard Code for Information Interchange) of any String entered by the user.
Code:-

import java.util.*;
public class StringASCII{
    Scanner scan=new Scanner(System.in);
    String string;
    int ascii;
    char asc;
    public void input(){
        try{
            System.out.println("Enter any String: ");
            string=scan.nextLine();
        }
        catch(Exception e){
            System.out.println("Error Code: "+e);
            System.exit(0);
        }
    }

    public void compute(){
        for(int i=0; i<string.length(); i++){
            asc=string.charAt(i);
            ascii=(int)asc;
            System.out.println("ASCII Code of \""+asc+"\" is: "+ascii);
        }
    }

    public static void main(String[] args){
        StringASCII ascii=new StringASCII();
        ascii.input();
        ascii.compute();
    }
}

Output is Like:
Enter any String:
ASCII CODE
ASCII Code of "A" is: 65
ASCII Code of "S" is: 83
ASCII Code of "C" is: 67
ASCII Code of "I" is: 73
ASCII Code of "I" is: 73
ASCII Code of " " is: 32
ASCII Code of "C" is: 67
ASCII Code of "O" is: 79
ASCII Code of "D" is: 68
ASCII Code of "E" is: 69
