Question

java中jlist信息修改

这个用的是jlist，选中第一个后下面的信息还是第二个的，怎么同步信息啊

Answer 1

String[] data = {"one", "two", "three", "four"};
JList myList = new JList(data);

// Create a JList that displays the superclasses of JList.class, by
// creating it with a Vector populated with this data

Vector superClasses = new Vector();
Class rootClass = javax.swing.JList.class;
for(Class cls = rootClass; cls != null; cls = cls.getSuperclass()) {
superClasses.addElement(cls);
}
JList myList = new JList(superClasses);

// The automatically created model is stored in JList's "model"
// property, which you can retrieve

ListModel model = myList.getModel();
for(int i = 0; i < model.getSize(); i++) {
System.out.println(model.getElementAt(i));
}
你要从0开始。

追问

我也想从0 开始，老师什么都没讲，我只学了一个学期最基础的java，而老师只给3天多的时间来完成整个程序，我也没办法啊.有没有具体点的代码
