Local variable x is never read.

[Hunter100]

Hello all,

I was watching a Java tutorial on YouTube about variable arithmetic. So I thought I'd make a simple programm to take two variables and do arithmetic on them. So I declare an int variable x. Then this happens:

I hover the mouse and it says "Local variable x is never read". What is this?

public
class Variable_Arithmetic {

 
         publicstaticvoid main(String[] args) {

 
                     int x = 10;


}

}

I am using Eclipse for whatever it's worth.

Help would be great.

It's just a 'warning' probably because you declare x. But you don't do anything useful with it. If below you say

System.out.println(x);

then it's most likely solved as eclipse notices that x is now used and useful in some way.
