hi.. im an amateur in java and im having problems in switch statements..
i would appreciate if you would help me solve this problem..

Problem: Write a java program that will let the user input 2 colors and display the result color..


This is what i come up with.. and the error is "incompatible type"

import java.io.*;
public class Projedential {

    public static void main(String[] args)throws IOException {

   	BufferedReader xan=new BufferedReader(new InputStreamReader(System.in));

	String white,black,red,blue,green,cyan,magnta,yellow,pink,brown,orange,violet="";

   	System.out.println("*****************************************");

   	System.out.println("Enter Color 1 :");
   	String c1=xan.readLine();

	System.out.println("Enter Color 2 :");
    String c2=xan.readLine();

	//if switch WHITE
	if (c1.equals("white")) {

		switch (c2)
		{

The 'switch' statement cannot work with String type. It works with integer (or may be long) number only...

By the way, this is not Java forum, it is JavaScript forum. Hope a moderator would move it to the right place...
