代码如下
//HelloToJava.java
import java.awt.Graphics;
import java.applet.*;
public class HelloToJava extends Applet {
public String sHello;
public void init() {
sHello="欢迎来到Java世界！";}
public void paint(Graphics g){
g.drawString(sHello, 50, 50);}
}
以上代码运行成功了
下面的代码却出错；
<HTML>
<APPLET CODE="HelloToJava .class"
WIDTH=200 HEIGHT=100>
</APPLET>
</HTML>
错误提示：
