Question

Hi I have the following code:

  boolean result = someexpression();

            if(!result)
            {
            System.out.println("False..."); 
            }
            if (result); 
            {
                System.out.println("True");
            }

It prints both (False and true)
I also tried using things like

     if(result==true)

but that doesnt seem to do the trick. No matter what the value of the variable it just enters the condition.?? I am using eclipse and this only happens at a specific portion.

Answer 1

if (result); 

Remove the ; at the end of this line.

With the ;, it means “if result is true, then do nothing”. The block that contains the next statement isn’t part of the if and will always be executed. It’s exactly the same as this:

if (result)   // if result is true
    ;         // then do nothing

System.out.println("True");  // is always executed
