Q1.what is the diffrence between Lightweight & Heavyweight Objects ?

viswagb:
In terms of Java GUI objects

Lightweight Objects are drawn/painted onto a blank window
No peer classes are required.
example : SWING objrcts are lightweight objects

Heavyweight Objects have a peer counterpart in the platform's OS.
example AWT objects are eavyweight Objects


Q2.What are the ways we can design a LightWeight
Object.

viswagb: use o/s independent object creation.

Hi,
In while creating GUI using Applets and Swings the lightweight and heavy weight topic comes in picture here applets uses the C and C++ code this is known as Machine specific code so it is known as haevy weight components and in if u use swing it is tottaly written in java it will now use any machine specific code so what it is known as light weight component

regards
Prabhu

if you JFC swing objects from Sun they are all light objects, if you use AWT then they are heavy weight..

I read once that Lightweight objects have transparent backgrounds and Heavyweight objects have opaque backgrounds.
