Java Scanner get char

Question

import java.util.Scanner;

public class myClass {
    public static void main(String[] args)
    {
        String[] exampleString;
        char expression;
        Scanner getExp = new Scanner(System.in);
        while(expression = getExp.next().charAt(0))
        {
           // myString will added by expression character
        }

    }
}

I tried it on Eclipse Mars but

expression = getExp.next().charAt(0) part gets error always.

I didn't understand that what is the error .

Previously i think on this link stackoverflow Scanner question

am i think wrong ?

Your while statement does not make any sense as it does not return a boolean. — LordAnomander, Dec 23 '15 at 12:35
You might not understand the error, but you should post the exact error text in full in your question: somebody here will! — Andy Turner, Dec 23 '15 at 12:37
It might not have a suggestion of how to fix the error, but it does have an error. — Andy Turner, Dec 23 '15 at 12:40

You probably want

while (getExp.hasNext()) {
    expression = getExp.next().charAt(0);
    ...
}
