Thread: Boolean value prints out the wrong one.

I am making a text adventure for a simple project as a java beginner, and it caught my mind that no matter if the value is true or false, it always prints out as if it was true. I took the liberty of making a new project in eclipse and tested the theory by itself. It is still the same. Here is the code:

public class BooleanLogic {
 
	static boolean test = false;
 
	public static void main(String[] args) {
		if(test = true) {
			System.out.println("true");
			System.exit(0);
		}
		if(test = false) {
			System.out.println("false");
			System.exit(0);
		}
	}
}

its output is always true!

you make an assignment:

test = true means in java that you set the var test to true. And in java the assignment return its value so it allways true

Give (test == true) a try.

P.S.
In pascal everything is easier, the math way anyway(insider joke)

I only used System.exit so it would close after it printed out the value.

Just a hint from a programmer, it's bad style to exit methods or return values in functions in more than one line. I didnt mean it in a bad way.

Fail... I haven't used java in a while, I won't tell you what I have been using since i may get banned :/
