I want to add a table table like this....using java awt and add button and i need to do add,update and delete in java

Correct me if things have changed, but last I remember awt didn't have a table class. I remember having to to stack text fields to simulate tables back then. You might want to try Java swing in which case a solution can be proffered.

im ok with anything
but cant drag n drop fro designer, Need to code it out and All the button panel etc.

I hope its not too late, been busy with work. I was able to whip together something minimal. I hope it helps. I advise you study the code and understand how they fit together. Laying out control in Java is very flexible, the same layout can still be achieved using other types of layout managers. PS: I haven't used Swing in a while as I have been working with JavaFX as far as java is concerned, so pardon any errors (I tested the code though and it works just fine). Also the data is stored in-memory, you can create a custom table model if you want to work with a database. Cheers.

You can access the code here https://ideone.com/ojzpTS incase NL messes up the code.
