(beginner) Switch Statement

Hello, I would like to ask a question regarding a switch case of mine. I am new to Java(have dabbled in c++ a little though.)

In one of my classes I have a method designed to take a character as a parameter and return a string based on the appropriate case.

The problem is the string that is always being returned is the default "INVALID", could someone point me in the appropriate direction? I checked the java tutorial but it didn't offer me much help, is there a problem with comparing integer literals / character literals on the same switch test condition?

Code :

---

private String GetNumber(char number)
	{
		String numberString = null;
		if(Character.isLetter(number))
		{
			Character.toUpperCase(number);
 
		}
		switch(number)
		{
			case 'A': numberString = "Ace";
				break;
			case 2: numberString = "two";
				break;
			case 3: numberString = "three";
				break;
			case 4: numberString = "four";
				break;
			case 5: numberString = "five";
				break;
			case 6: numberString = "six";
				break;
			case 7: numberString = "seven";
				break;
			case 8: numberString = "eight";
				break;
			case 9: numberString = "nine";
				break;
			case 1: numberString = "ten";
				break;
			case 'J': numberString = "jack";
				break;
			case 'Q': numberString = "Queen";
				break;
			case 'K': numberString = "King";
				break;
			default : numberString = "INVALID";
				break;
		}
		return numberString;
	}

One thing that jumps out is your case numbers. You have them as ints but your switch statement variable is a char. You numbers should be '2' or '3' etc...

also you may have to take the input as a string and use the charAt() method.

I actually did use the charAt method to get that value.

Also the single quotes around my cases solved the problem. Thread marked as solved and a Thanks to you (;
