想在execute sql时可以中断
------------------------------------
Thread th=new Thread(){
            public void run(){
                wait.getLb_Text().setText("Exquting,Please Wait!!!");
                wait.setVisible(true);
                wait.repaint();
                try{
                        stmt=conn.createStatement(java.sql.ResultSet.TYPE_SCROLL_INSENSITIVE ,java.sql.ResultSet.CONCUR_READ_ONLY );
                        rs=stmt.executeQuery(sql);
...............................
                        wait.setVisible(false);
                        wait.repaint();
                }                    catch(InterruptedException ex){
                        System.out.println("System interrupted");
                }
                
            }
};
        wait.thread=th;
        th.start();
-------------------------------------------------------------------在相应的 try 语句主体中不能抛出异常 java.lang.InterruptedException
                    catch(InterruptedException ex){
