ok so i have this

Code: Select all

String fn = JOptionPane.showInputDialog("Enter your first number");
		String sn = JOptionPane.showInputDialog("Enter your second number");
		String op = JOptionPane.showInputDialog("Enter either divide(1), multiply(2), subtract(3), add(4)");
		if (op<1){
			JOptionPane.showMessageDialog(null, "Not Applicable, must use numeral character or number may not be smaller than 1", "ERROR", JOptionPane.ERROR_MESSAGE);		
		}
		if (op>4){
			JOptionPane.showMessageDialog(null, "Not Applicable, must use numeral character or number may not be larger than 4", "ERROR", JOptionPane.ERROR_MESSAGE);			
		}
		
		switch (op){
		case 1:
			
		}

and you see where it says "String op" i dont want the variable op to be a String i want it to be a int or if i cant

how can i use switch with a string, not a number


btw im betting at least 6 bucks that mandai, zulf, or mike will answer the best

You should use this (C#):

Code: Select all

int number = int.Parse(op);

Is there a particular reason why this is in the JavaScript section? If this was JavaScript you would not need to worry about parsing as there are no strict rules on data types.

Use

Code: Select all

convert.tostring(whatever your int is)

to convert from an int to a string

or

Code: Select all

convert.toint32(your string here)

to convert from string to an int.

Hope this helps


Edit: Oh wait, are you doing this in VB.NET?

Dude Javascript, and Java are two completely different programming languages. Maybe you should take a look at this topic I posted on the Evolution of Computer Programming Languages.

Now by looking at your code it's Java, not Javascript, and that means this post belongs here.

Also I see your code is similar to one of the first Java tutorials I watched by Bucky (thenewboston) when you ever get into gui development. Here's something to get you started. (It's just a window, but once you get better you can add a file menu, images, etc:)

Code: Select all

import javax.swing.JFrame;

public class app {
	public static void main(String [] args) {
		new tapp();
	}

	private static class tapp extends JFrame {
		public tapp() {
			super();
			setTitle("TestApp");
			setSize(320,240);
			setLocationByPlatform(true);
			setAlwaysOnTop(false);
			setVisible(true);
			setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		}
	}
}
