I would like have one method declare two Strings and assign them values. Then have another method to read those values.

I have this structure:

```
public class ABC extends CDE implements EFG {
    public void firstMethod(valueOne, valueTwo) {
        class TestClass {
            public String testValue = valueOne;
            public String anotherValue = valueTwo;
        }
    }

    public void readMethod() {
        // HERE I WANT TO READ testValue AND ASSIGN IT A NEW VALUE
    }
}

```

How can I do that? 

And is there a better way?
