Ternary operator

I didn't say that ternary operator is a statement. What I'm saying though is that you should be able to place expressions into this operator.

This operator suppose to be a shorthand for if then else so why I can write something like:

if (i == 0)
{
tmp.setVisible(true);
}
else
{
tmp.setVisible(false);
}

but not as I wrote in my original post?

You would not expect the following to be working would you?

public void testExpression() {
1+1;
}

Well as a matter of fact I would indeed expect that to work. Why wouldn't I ? If it is correct java syntax, and 1+1 is I would expect correct syntax to work.

It's another of java's illogicalities. In my code mentioned in original post if I have to use a ternary operator to do what I want it to do:
1. I have to make sure that I'm using methods which return some value different than void and
2. I have to assign it to some completely unnecessary variable.

So following this logic I can't say:

int == 0 ? setVisible(true) : setVisible(false);

but providing that I have method definition:

int setSelectable(int a)
{
//do something
//and just for sake of making this to work I have to have return statement
return a;
}

having that now I can write

int a = i == 0 ? setSelectable(1) : setSelectable(0);

Pathetic, illogical and completely java like behavior.
Guys, I'm telling you, every time when I have to do something in java I just get irritated and frustrated. Something what in other languages is simple and logical and work as you would imagine it to work in java is very often somewhat different, illogical and annoying.

Another thing is that it is an operator just like '+' or '-' and as long as it have correct operands on each of its side it should work without making any problems.

Your gross misunderstanding of the basics suggests that you should refamiliarize yourself with the simple concepts. I suggest starting here . I also suggest dropping the attitude before you ask any more questions.

It happens that I have c++ background and in c++ this kind of syntax works. There is no need to get agitated. I am not saying to anyone to change programming language. The only thing I'm saying is that in java, very often things works in illogical way which frustrates me. I think I have right to get frustrated if something doesn't work in a logical way. And don't give me any suggestions.

What? Why? Says who? This doesn't make any sense.

Why this:
1+1
doesn't make any sense to you?

So, let me get this straight: you don't know how to use a ternary operator, so instead of learning and correcting yourself, you conclude that java must be in the wrong?
If you can't grasp the simple concept behind the ternary operator's behavior, maybe it's time to consider a career change?

I just want to point out that in my original post I 've used this operator correctly, but because java doesn't behave logically (sometimes), I was getting an error.
