If you have return type int then you have to return something.

Your first SOP statement is showing error because you are printing after returning value. So SOP will never execute because program returned before that.

No need to return in every if else. Just declare a variable, assign value then return at the end of if else statement.

If you don't want to return then don't call your method in this case.

So finally, your code should be like this:

Answer 2

Yes you have to return an integer value like -1 in final else.
And first use System.out then return

Answer 4

NotHuman i don't want it to return anything if the score range is less than 0 and greater than 100.

I returned -1, but my first S.O.P statement is showing an error message of "Unreachable Statement"
