i am new for java programing world.
can you help me for above thread.

First and foremost, make sure you work through the official Java tutorials offered by Oracle (the "Trails covering the basics" section) to get a hang of things.

After that, picking up tutorials depends on the kind of project you are interested. Interested in developing web applications? Head over to the Java EE tutorial section. Interested in creating UI's? Head over to the "Creating graphical interfaces section". All in all, work out the basics and then post again so that the members here can give you specific advice.

If you are feeling rather adventurous, also have a peek at the sticky placed at the top of the forum which brings together all the resources you might want to refer as a beginner.
