im little confused..
a class contains 2 methods...for ex..lets take Toolkit class in awt package...it constains 2 methods, what does it mean when u write class.method1().method2()
method2() is returning something
method1() is returning something else...
for ex..in the below statement...
x=Toolkit.getDefaultToolkit().getImage"MyPicture.jpg");


please use the [code][/code] tags when showing code. visit <a href="http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=ubb_code_page" target="_blank" rel="nofollow">http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=ubb_code_page</a> ,for more details

you're just invoking two methods. For example Say I had variable of type String:
String a;
And I wanted to get 4.5 rounded.
I would simply say:
a= Math.round(4.5).toString();
In this example the number 4.5 is rounded, and then that number is converted to a string. Do you get it?

hi sean i got it,but this raises some more doubts....
1)
can we link any no.of.methods like this fashion....
x= class.method1().method2().method3().method4().....or is there any constraint for it.....and
2)
if 1) above is true, is it evaluated like....
class.{{{{method1()}.method2()}.method3()}.method4()}

I think you'd be better off if you start coding these things yourself, and testing them. You tell me if you can do that.

I'm still willing to help,I just think you'd get more out of it if you tried it out yourself.
to answer you question you can chain methods as long as it makes sense.
For example I couldn't do the following:
int a= (int)math.round(5553.234343).repaint();
Obviously repaint() doesn't belong there, but you see what I mean. Right?
