Should keyword return be at the end of method always?

Answer 1

if a method has a return type there must be a return at the end of the method, but it is possible to put return statments earlier in the method, but keep in mind once a return statment is hit the rest of the method does not get executed.

Answer 2

Most compilers also throw a warning (or even error) for anything that comes after return, something along the lines of "unreachable code"

Answer 3

No, if it's a method returning void the return keyword is not necessary at the end of the method.

Answer 4

+ if return is only inside if() block (without else) you get
error: missing return statement

int method(){
if(true) {
return 100;
}
// return 0;
}
