小程序未初始化

Question

I am writing this code and trying to run it using appletviewer .

import java.awt.*;

import java.applet.*;

public class FirstApplet extends Applet
{

/* <applet code="FirstApplet" height=200 width=300>
</applet> */

    public void paint(Graphics g)
    {
    g.drawString("First Applet program ",50,30);
    }
}

I'm compiling it by javac FirstApplet.java and running it with appletviewer by writing Appletviewer FirstApplet.java

But, the problem is that I'm not getting the expected output . Indeed it's just showing that the applet is not initialized .

Can anyone help me out with the above? What should I do to make it run properly? I'm running Windows 7, on a dual core processor with 3GB of ram. The version of java is jdk1.7.0_45.

Answer 1

Appletviewer requires a that the class be loaded from a HTML file containing an applet tag

<applet code="FirstApplet" height=400 width=300></applet>

Some side notes:

• It's considered good practice to declare classes in packages.
• java.applet.Applet is incredibly old. Take a look at Swing's JApplet
