If you put a return statement in the if
, while
or for
statement then it may or may not return a value. If it will not go inside these statements then also that method should return some value (that could be null). To ensure that, compiler will force you to write this return statement which is after if
, while
or for
.
But if you write an if
/ else
block and each one of them is having a return in it then the compiler knows that either the if
or else
will get executed and the method will return a value. So this time the compiler will not force you.
if(condition) { return; } else { return; }
