My if statement ALWAYS returns true, no matter what
Question by user1364363
This just is’t making sense to me at all.
This is my code:
boolean that = false;
if (that == true);
{
System.out.println("That is " + that);
}
And yet it will print the line even though my output is
That is false
I’m doing this in java and I’m using Eclipse galileo, so each time I compile/run my program it saves it so the compiler should be getting updated version of my program.
What’s going on?

A common mistake. Remove the ; at the end of the if statement.
BTW I always write the following if I use brackets and I use the code formatter of the IDE.
if (that == true) {
System.out.println("That is " + that);
}
This means if you have a mis-placed ; or { it can be more obvious.

if (that == true);
// ^ The extra colon you dont need
