The question I asked might be closed, But i just want to know that is it necessary to write else part of every if condition. One of my senior programmer said me that "you should write else part in every if condition" . Suppose we have no condition for write in else part then what should we do ? I assume a healthy discussion will going on here....

That's a horrible idea. You end up with code of the form:

if (something) {
    doSomething();
} else {
}

How anyone could think that's more readable or maintainable that not having an else at all is beyond me. It sounds like one of those rules made up by people who have too much free time on their hands. Get them fired as quickly as you can, or at least move away calmly and quietly :-)
