assertTrue not working

[kraigballa]

I have the following test case, but it's not working even though the values do match up. Anyone know what's going on?

try {
			String str = InfixToPostfixParens.convert("(6 + 6) * 2");
			System.out.println(str);
			assertTrue(str == "6 6 + 2 * ");
		} catch (InfixToPostfixParens.SyntaxErrorException e) {
			e.printStackTrace(); 
		}

The output I get from the print statement is

6 6 + 2 *

Which matches what I have in my assertTrue...

The space after the asterisk is there in the str print

Conratulations! You're the kazillionth person trying to compare two Strings for equality with the == operator; it doesn't work; read the API documentation for the equals( ... ) method in the String class.

kind regards,

ARG!!!! I'm used to PHP not Java quite yet. Both should work in all reality though...

Why do you think 'both should work'? The way to compare two Strings for equality in Java is using the equals( ... ) method, no matter how much you wish it to be otherwise.
