Java 小程序不显示任何内容 [英] Java applet does not display anything
问题描述
有谁知道为什么我的 Java 小程序不显示任何内容?
Does anyone know why my Java applet does not display anything?
这是我的第一个 Java 小程序，所以我是创建一个的新手.我研究了这个问题，但没有找到针对当前问题的答案.
This is my first Java applet so I am new to creating one. I researched this problem and haven't found an answer specific to the current problem.
import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Font;
import java.awt.Color;
public class JavaRocksApplet extends Applet
{
public void paint( Graphics screen )
{
Font f = new Font( "TimesRoman", Font.ITALIC, 36 );
screen.setFont( f );
Color c = new Color( 40, 80, 120 );
screen.setColor( c );
screen.drawString( "Java Rocks!!", 100, 60 );
}
}
我在命令模块或 html 页面中使用 appletviewer 都没有关系.
It doesn't matter whether I use appletviewer in the command module or an html page.
<html>
<head>
<title>JavaRocksApplet</title>
</head>
<body>
<applet code = "JavaRocksApplet.class" width = 400 height = 200> </applet>
</body>
</html>
编译Java程序时没有错误，所以我有点困惑为什么它不起作用.
There are no errors when compiling the Java program, so I am a little bit confused about why it doesn't work.
此外，我使用的是运行 OSX 10.8.2 Mountain Lion 和 Java SE 6 的 MacBook Pro
Also, I am using a MacBook Pro running OSX 10.8.2 Mountain Lion with Java SE 6
推荐答案
这是此工作代码的屏幕截图.除了从指定的小程序高度缩短.
Here is a screenshot of this working code. Except shortened from the applet height specified.
所以，正如 Neet 在评论中指出的那样.'它在这里有效.'
So, as Neet noted in a comment. 'It works here.'
import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Font;
import java.awt.Color;
/*
<applet code = "JavaRocksApplet.class" width = 400 height = 200> </applet>
*/
public class JavaRocksApplet extends Applet
{
public void paint( Graphics screen )
{
Font f = new Font( "TimesRoman", Font.ITALIC, 36 );
screen.setFont( f );
Color c = new Color( 40, 80, 120 );
screen.setColor( c );
screen.drawString( "Java Rocks!!", 100, 60 );
}
}
可能可以通过查看控制台找到有关问题实际原因的更多详细信息.请参阅如何启用和查看 Java 控制台?
Likely more details on the actual cause of the problem can be found by viewing the console. See How do I enable and view the Java Console?
