Selection a row in the JTable per single mouse click and restriction of the selection

[Olena Golub]

Hello Java-Gurus!
I have some questions about JTable.
How can I implement in the JTable that I can select only maximum three rows in the Table?
And the second question is:
How can I implement this?:
I select one row per single mouse click. Than I select the second row per single-mouse click (without Ctrl). The fist should be also selected.


I am very thankful for your help or ideas!

I did it!
It works now

public class MyDefaultListSelectionModel extends DefaultListSelectionModel{
        public MyDefaultListSelectionModel (){
            super();
        }
 
        public void setSelectionInterval(int index0, int index1) {
            if(table.getSelectedRows().length==3)
                return;
            
 
            if (isSelectedIndex(index0)) {
                super.removeSelectionInterval(index0, index1);
            }
            else {
                super.addSelectionInterval(index0, index1);
            }
    }
   }
