一个在网上获取图片的java程序..
imag.java文件..
import java.applet.*;
import java.net.*;
import java.awt.*;
public class imag extends Applet
{
Image imag;
URL imgur=null;
public void init()
{
try{
imgur= new URL("http://img.poco.cn/photo/20060721/94378020220060721123628_3.jpg");
}
catch(MalformedURLException e)
{
System.out.println("Can´t open the URL");
}
imag=getImage(imgur);
}
public void paint(Graphics g){
g.drawImage(imag,0,0,this);
}
}
test.html文件:
<html>
<head>
<title>Example</title>
</head>
<center>
<applet code=imag.class width=550 height=230>
</applet>
</html>
编译javac imag.java,没有错误..
运行appletviewer test.html..怎么不显示网络上的图片...给出这些提示..
