Listing 2-20. Testing the ModifiedOuter2 Class
// ModifiedOuter2Test.java
package com.jdojo.innerclasses;
public class ModifiedOuter2Test {
public static void main(String[] args) {
ModifiedOuter2 out = new ModifiedOuter2();
ModifiedOuter2.Inner in = out.new Inner();
// Print the value
out.printValue();
in.printValue();
// Set a new value
out.setValue(828);
// Print the value
out.printValue();
in.printValue();
}
