one you make a b=new Checkbox("Checkbox_1");
b is a reference to a new object
when you do add(b) you add a reference to the "current" b to
you're applet.
in you're example
b=new Checkbox("Checkbox_1"); | b has a refernce to a checkbox
add(b) | the applet keeps a reference to the checkbox
b=new Checkbox("Checkbox_1"); | b is now a ref to another check
add(b) | the applet now keeps a ref to the first and the second
