Your methods have no logic to them. Basically you're making a recursive call to a method that will never break out of the loop.

public void sendMail()
{
int y = 300;
name = "Vinay";
age = 26;
sum();
sendMail(); // It is also recursive but not showing any error.
}
}

This Code Will not give any error at compile time.
But at the time of running this code sum() will called recursively and a never ending process until unless you did not stop the execution explicitly or any MemoryOutOfBound exception occurs.

you are running into an infinite loop.... method sum() has no end..
And sendMail() method is never invoked in main(), hence you got no error there.
