multithreaded tablemodel - mutexes?

Hi

Ok I have a JTable with a TableModel extending DefaultTableModel.

All my calls goes through JTable to TableModel.

for example:

first invoked:

//In JTable

publicvoidsynchronized doSomethingWithRows()

{

int rows = tableModelName.getAllRows();

for(k=0; k<rows; k++)

{

System.out.println("TESTING!");

}

}

PROBLEM: In the above method doSomethingWithRows an OutOfBoundsException can occur ! because apparently the TableModel can change meanwhile(even though I have synchronized the entire method) from another thread.

Andthis is the method its calling...

//In TableModel

publicsynchronizedint getAllRows()

{

int rows= getRowCount();

return rows;

}

I apparently need to lock the tablemodel and would need some kind of mutexes. How do I lock an object in Java?

thx!>
