Simple Question: ValueChanged Event in Java

Question

Is there an event in Java that fires when a value changes? Like in this example

public class Example{
    public String var1 = \"Something\";
    public Int var2         


        

Answer 1

I think you might be looking for the "observer" design pattern (Wikipedia Entry)

This is implemented in java via extending Obserable and having objects that want to be notified implement the Observer interface.
