The message is quite clear. You are using the value 9 to access something in an array which only contains 4 elements. However we have no way of telling why that happens. You will need to use your debugger to capture more information.

Member 15493982 19-Jan-22 21:02pm

No no,some time it can be value 0 out of bounds for length 0.
It like : Index X out of bounds for length Y (X,Y is a number)
And I don't set length for text field

Well you still have to use your debugger to find out where it is happening and why. It is impossible for anyone here to guess what your code does.

Member 15493982 20-Jan-22 4:39am

I see two:
table.getSelectionModel().addListSelectionListener(
new ListSelectionListener() {
@Override
public void valueChanged(ListSelectionEvent e) {
selectedrow = table.convertRowIndexToModel(viewrow);
}
}
);

sorter.setRowFilter(rf);

And as I keep suggesting, you can only find the answer by using the debugger and finding out where, and why, these invalid indexes are being generated.

I know my problem. It is because I selected row then I enter text in Jtextfield, and when filter start, this statement:
selectedrow = table.convertRowIndexToModel(viewrow);
will error. Can you help me fix it

Check this thread, you could find suggested fix.

JDK-8032874 : ArrayIndexOutOfBoundsException in JTable while clearing data in JTable[^]

Basically you need to add if condition for convertRowIndexToModel line where you're getting error.
