Making ArrayList to JTable

Question

I have an

ArrayList>

Object, I need to display the content of this array in a JTable.

The Map - Ke

Answer 1

ArrayList>

This sounds like the wrong model for the job, there is not really a sensible way of turning this into a single table. Perhaps you mean

This would make a lot more sense. Now one single key (the column name) is mapped to multiple values (the column values).
