this example is only used java bean.
I think the uses of java bean and form bean are different.
I think Form bean is part of view layer and Java-Bean is the part of model layer.
But I am little bit confuse How to use these two and How to decide Where I use?...

Correct code for class a and claas z as follows -
...Code:public class Z { public static void main(String a[]){ A az = new A(); System.out.println(az.ax.getY()); //null Pointer exeption } } class A { X ax; A(){ ax = new X();Leave a comment:
