class WHWWW{
public static void main(String[]arg){
URL u=new URL("http://www.whitehouse.gov/");
InputStream ins= u.openStream();
InputStreamReader isr=new InputStreamReader(ins);
BufferedReader whitehouse=new BufferedReader(isr);
System.out.println(whitehouse.readLine());
System.out.println(whitehouse.readLine());
System.out.println(whitehouse.readLine());
System.out.println(whitehouse.readLine());
System.out.println(whitehouse.readLine());

}
}
程序如下，报错原因不清楚。

异常没处理，
还有流用完记得关闭啊。
我帮你改了，你去看下异常和io，能懂的
