Return to Question

I am new to java. I want to know how I can use the variable in the whole java class and keeping the value of it. Suppose in a method I fill the variable with a value and I want to use the value of it in another method.

public class Test {
    public String id;

    public void includeClient() {
        String id = baseClass.createCleint();
    }

    public void includeClient() {
        System.out.println(id);
    }
}

in second function it returns null. Any idea?
