I'm having some problems writing a method that will take two integers and add up the sum of the integers and all the numbers between them. Ex. the int are 3 and 7, the method does 3+4+5+6+7 and returns 25.

What I have so far is:



I still have to write a portion showing what happens when num1 and num2 are equal, but... when I try to compile what I have so far I get the following error:

C:\Documents and Settings\Brad\Desktop\CSE\Geek.java:75: missing return statement
}
^

When I comment that section of my code out it compiles, so I'm sure that's where the problem is but I can't see what return I'm missing (I'm terribly new at java). Am I even close?

Any help would be appreciated.

This is actually pretty good considering that you're new to Java. The problem that you're having is that your return statements are inside of the for loops.

Because of your two if conditionals, you don't take into account that num1 = num2, so if that is the case, neither of the if statements are ever true, and therefore, no value is ever returned.

So here's the solution:
take the two pieces of your code that say, return sum, and put it at the very end of your code (just before the last bracket of the method. This will work because in both of the if conditionals, the value you want to return has the name sum.

One thing you may want to look out for is if num1 = num2, because you may be returning the variable sum, which hasn't ever been initialized. To fix this, I would advise declaring the variable sum in the begining of the method and give it an initial value of either 0, or -1.

Good work for just starting. Keep up the good work.

That fixed it right up, I knew it was something simple like that (isn't it always?). Thanks a ton!
