What's the output of this guy here? (don't cheat;)

So Java doesn't do implicit integer-to-boolean (0 - false and 1 - true). Thus you get a compile error here. @i_sopov got there first!

@EclipseJavaIDE (not cheating) does Java do a sort of zero -> false, nonzero -> true kinda thing? In which case it'd print "-1" since the loop condition isn't true on the first iteration, and s is never increased

@EclipseJavaIDE It should not compile, I think

@EclipseJavaIDE should’t compile: 0 = false; 1>= true; -1 <= error;

@EclipseJavaIDE Get compile time error because in the if condition it will check for boolean value. But we are giving integer

@EclipseJavaIDE Compilation Error as condtitional expression is missing in for loop

@EclipseJavaIDE -1

@EclipseJavaIDE Compile time error

@EclipseJavaIDE I think it should be -1. As i will be 0 (i.e. false), the condition fails at first iteration itself and value of s will be as is.

@EclipseJavaIDE -1

@EclipseJavaIDE Compile time Exception

@EclipseJavaIDE Exception because the condition in the for loop is not set.

@EclipseJavaIDE Error error for

@EclipseJavaIDE -1

@EclipseJavaIDE Throws an error for the condition is not specified.

@EclipseJavaIDE Compilation error

@EclipseJavaIDE Compilation error - The type of the termination expression is an integer value. Expression should be constructed in such a way that it returns a Boolean value True/False. Upon executing this code an Exception will be generated which will indicate a compilation error.
