Code tags added. Please read my signature link to learn how to use these yourself.

You should never have a semicolon at the end of an if boolean test as that will short circuit the if. The compiler thinks that you want to call an empty block if the if statement is true.

So this:

if (4 == 3);
  System.out.println("foo");  // why is this line always called?

Is actually interpretted by the compiler to this:

if (4 == 3) {
   ;
}
System.out.println("foo");  // Now we see why the line is always called

Better to do this:

if (4 == 3) { // no semicolon now and braces added.
  System.out.println("foo");
}

Also, always enclose all blocks in curly braces.

Luck and welcome to the Java-Forums!

Also, always enclose all blocks in curly braces.

Which help you to avoid unexpected errors in your code, and some may very difficult to track at once. And also it's very clear the code, easy to read, not only for you for other as well. Keep theses practices with you all the way. :) Good luck!
