I already know the codes to display the results from table like select * from and bla bla. But I want to display ANY result from mysql to netbeans. For ex.-> If user says "show databases", it should display databases in textarea and same is for tables. I mean, no matter whatever user wants to see, whether its seeing the table or databases or columns or what, the result should appear in textarea. And i possibly cant go on writing commands for each of these actions since there are so many possibilities. So please, is there any way to display all the results from mysql into textarea in java? Thanks.
EDIT: Well... I got netbeans (yeah i am a little new to this stuff) and so far this is my code. I want the result to be displayed in a text area. Here is coding for frame in which the textarea exists where i want results to appear- >
