package homework1;
import java.applet.Applet;
import java.awt.Graphics;
public class Homework1A extends Applet {
public void paint( Graphics g ){
g.drawString("CIS 35A Student Learning Outcomes ",40,60);
}
}
这是我收到的警告
The serializable class Homework1A does not declare a static final serialVersionUID field of type long
Homework1A.java /homework1/src/homework1 line 5 Java Problem
还有另一个类似的警告
Warning: Can't read AppletViewer properties file:
但在我运行代码几次后它就消失了。
最佳答案
您的类中需要一个串行版本 UID，例如:private static Final long serialVersionUID = 1L;。
您可以将此作为引用:Serial IDs
