How to use variable in void to declare another variable Java?

Question

So I'm making a Java Util and I am stuck on this part of code.

public void getInput(String i){
    int i = scan.nextInt()
}

Why won't this work?

Give your variables more descriptive names. – nhgrif Nov 14 '13 at 02:18 — nhgrif, Nov 14 '13 at 02:18
What exactly is the problem? Is there an error? – Szymon Nov 14 '13 at 02:37 — Szymon, Nov 14 '13 at 02:37

i is already declared as String yet you redeclare i as an int. That can't work!

What I was trying to do about 3 months ago was use the name of String i to name the int. But, i chnged it around: – javaboy Jan 17 '14 at 16:24

You have two variables, which has the same name i but has the different type.

Change it like,

public void getInput(String i){
    int data = scan.nextInt();
}

and the Complier error will be gone.

But I need the String to be identified as i. So if a Dev types getInput(stackoverflow) it should ask for input and store it under int stackoverflow so they can case(stacloverflow) – javaboy Nov 14 '13 at 03:38
