Character Identification Program (Java)

I coded the following program in Java. The program will identify characters.

Please page down to see the coding.

package javaapplication7;

//import java.lang.*;
import java.util.Scanner;

public class JavaApplication7
{
    public static void main(String[] args)
    {
        int jchar = 0;
        Scanner input = new Scanner(System.in);

        //int to char

        System.out.print("Enter int: ");
        int i = input.nextInt();
        System.out.println("char value: " + (char)i);
        System.out.println();
        //char to int
        
        System.out.print("Enter chars: ");
        String s = input.next();
        System.out.print("int value: ");
        
        while(jchar<s.length())
        {
            System.out.print((int)s.charAt(jchar) + "(" + s.charAt(jchar) + ")");
            jchar++;
        }
        
        System.out.println();
    } // method main

} // end class
