i m declaring a method with syntax .....
public void addWidgets() {
no you have private but either way you can't throw in code for one method all willy-nilly inside of another method or constructor.
take the code for your addWidgets out an put it at the end of your file and then where you call it in the constuctor is should just be addWidgets();
