import java.awt.*;
class Scroller extends Frame{
public Scroller(){
List movieList = new List();
movieList.addItem("亲情树");
movieList.addItem("男才女貌");
movieList.addItem("激情燃烧的岁月");
movieList.addItem("宰相刘罗锅");
movieList.addItem("铁嘴铜牙纪晓岚");
movieList.addItem("年轮");
movieList.addItem("英雄");
ScrollPane scroller = new ScrollPane(ScrollPane.SCROLLBARS_AS_NEEDED);
scroller.add(movieList);//加入子组件
Adjustable vadjust = scroller.getVAdjustable();
Adjustable hadjust = scroller.getHAdjustable();
hadjust.setUnitIncrement(20); //设定水平自增单位
vadjust.setUnitIncrement(20); //设定垂直自增单位
scroller.setSize(100,100);
add("Center",scroller); //加入BorderLayout布局中
pack(); //按组件的尺寸缩放窗口



}
public static void main(String[] args){
Scroller test = new Scroller();
test.setVisible(true);
}

}
求解释！！！

说明这个方法过时了~找其它方法替代使用！
在帮助文档里面应该会有写！
但是好像也是可以运行的吧

过时API尽量不要用，如，
movieList.addItem("亲情树");
最好写作：
movieList.add("亲情树");

Hi haidi3743660,

If you read java source code, you will find some methods have some annotations like @Deprecated.
It means the method maybe is being removed in the next jdk version.You can use it in present jdk version.The compiler give you a warning to suggest not using it.I think if you understand the meaning of it ,it's just ok.

Sorry for my poor english ,I just practise.If I have anything fault ,please contact me.
Thanks.
