当我删除JTable的最后一行时超出范围异常

Question

如果我们在表中有n行并删除其索引为n-1的行，则此代码为Ok，但是当我删除其索引为n的行（或删除行之后的任何行）时，我会捕获索引约束异常！ 我该如何解决这个问题？

 Thread registerThread = new Thread(){
    public void run(){
        try{
            int i =JOptionPane.showConfirmDialog(view, "Are you sure to delete these IP and port?" );
            if(i == 0){
                int selectedRow = workerMachineTable().getSelectedRow();
                System.out.println("selected row" + selectedRow);
                unRegister(selectedRow);
                dataModel.removeRow(selectedRow);
            }else return;
        }catch (Exception e){
            JOptionPane.showMessageDialog(view, e.getMessage(), "Error", 2);
            e.printStackTrace();
        }
    }
};

从所选行中减去一个

  int selectedRow = view.getWorkerMachineTable().getSelectedRow() - 1;
