------解决方案--------------------
没时间看,凑个数先
------解决方案--------------------
myFrame.getContentPane().add( "Crenter ",jt);

//ERR:adding a window to a container

------解决方案--------------------
主函数这么写：
public static void main(String[] args) {
myFrame = new ListComboxEaxmple();
myFrame.setSize(200,200);
myFrame.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent e){
System.exit(0);
}
});
myFrame.setTitle( "列表框和组合框实例 ");
myFrame.setVisible(true);
}
------解决方案--------------------
提示信息不是已经写的很清楚了吗，楼上的
