import java.awt.*;
import java.applet.*;
public class Applet1 extends Applet{
public void paint(Graphics g){
this.setBackground(Color.red);
g.drawString("aaaaaaaaaaaaaaa",20,50);
}
}
3: class Applet1 is public, should be declared in a file named Applet1.java
import java.applet.*;
public class Applet1 extends Applet{
public void paint(Graphics g){
this.setBackground(Color.red);
g.drawString("aaaaaaaaaaaaaaa",20,50);
}
}
3: class Applet1 is public, should be declared in a file named Applet1.java
你肯定没有将这个文件的文件名定义为Applet1.java.
因为public class 后面加的class名就是文件名.这是一定的
必须是静态方法呀
3.类Applet1是一个公有类 , 应该被定义为一个文件名为Applet1.java的文件.
报错写清楚了.文件名和类名要相同.
文件名必须和public类名一致
把文件保存成Applet1 .java
