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

By
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

Vanilla Javascript each()

By
JQuery's each() is very useful when iterating through elements. But you don't want to use JQuery in your project you can simply add the following javascript code which works somewhat similar to the JQuery's each function. Here the fnc parameter is the function string which is converted to a valid function call replacing all the $(this) with this /**  * This function binds a particular function to every element with the specified selector. It is somewhat same as JQuery's each() with less functionality  * @param {String|DOMElement} selector  * @param {Function} fnc  */ function each(selector, fnc) {     var elem;     if (typeof selector === "string") {         elem = $_(selector);     } else {         elem = selector;     }     fnc = (fnc.toString().replace("$(this)", "elem") + "();").replace("function () {", "").replac...
