How do I use a character in a switch-case? I will be getting the first letter of whatever the user inputs.

import javax.swing.*;

public class SwitchCase {
    public static void main (String[] args) {
        String hello = "";
        hello = JOptionPane.showInputDialog("Input a letter: ");
        char hi = hello;
        switch(hi) {
            case 'a': System.out.println("a");
        }
    }   
}

Here's an example:

public class Main {

    public static void main(String[] args) {

        double val1 = 100;
        double val2 = 10;
        char operation = 'd';
        double result = 0;

        switch (operation) {

            case 'a':
                result = val1 + val2; break;

            case 's':
                result = val1 - val2; break;
            case 'd':
                if (val2 != 0)
                    result = val1 / val2; break;
            case 'm':
                result = val1 * val2; break;

            default: System.out.println("Not a defined operation");


        }

        System.out.println(result);
    }
}
