Java: Anonymous inner class using a local variable

Question

How can I get the value of userId passed to this method in my anonymous inner subclass here?

public void doStuff(String userID) {
    doOtherStu         


        

Answer 1

declare the method

public void doStuff(final String userID)

The value needs to be final so that the compiler can be sure it doesn't change. This means the compiler can bind the value to the inner class at any time, without worrying about updates.

The value isn't changing in your code so this is a safe change.
