I am getting the same error for both these codes(both different). I been trying to figure out the problem and tried other possibilities but I just can't seem to crack it. Can someone lend me a hand and point me to the right direction.

Code 1:

Code 2:

Btw, code 2 isn't complete yet but I just wanted to compile the code I had to see if I encountered any errors so far which obviously I am.

You want to compile and run against which version ? anyway, here are a couple of fixes that you probably want to make.

Ah. I see my mistakes now. Thank you, I definitely will remember these mistakes.

However, if I wanted to still use isEmpty() in the first code, how could I have used it correctly without the code getting complicated.

Also, is the length method in args.length from the java.lang.String? I am asking because I see a length() method in there but it has parenthesis after the length() so why wouldn't it be args.length()?

The variable "args" is an array (not a String), and "length" is a public field in an array.

This is described under JLS 10.7 Arrays.
