简单JTable显示Integer问题，请大家指教，急啊！

从新整理一下代码：为什么我修改Integer列时总抛出异常啊
ivjScrollPaneTable = new javax.swing.JTable();
ivjScrollPaneTable.setName("ScrollPaneTable");
ivjScrollPaneTable.setBounds(0, 0, 450, 400);
// user code begin {1}String[] names = {"姓名","性别","年龄","分数","及格"};
Class[] c = {String.class,String.class,java.lang.Integer.class,java.lang.Integer.class,Boolean.class};model = new javax.swing.table.DefaultTableModel(names,0){
public Class getColumnClass(int columnIndex){
return c[columnIndex];
}
};
java.util.Vector tmpv = new java.util.Vector();
tmpv.addElement("小麦");
tmpv.addElement("女");
tmpv.addElement(new Integer(23));
tmpv.addElement(new Integer(80));
tmpv.addElement(new Boolean(true));
model.addRow(tmpv);
ivjScrollPaneTable.setModel(model);

    Cannot format given Object as a Number俺也 没有看见什么错误
      

  3.   

    我才用 editPlus 配合 jdk1.4做了一遍，一切OK我用VisualAge for Java 3.5 就出错了，破VisualAge for Java，IBM都放弃他了，为什么我们公司还用他啊，支持的jdk版本还不到1.3（可能1.2.几吧）呢，破问题郁闷了我半天了，唉，我该怎么办啊，郁闷

    现在还有人用 VisualAge for Java 3.5  吗？
