Container cp=this.getContentPane();
cp.setLayout(new BorderLayout());
jp=new JPanel();
jl=new JLabel("输入网址",JLabel.LEFT);
jtf=new JTextField(20);
ta=new TextArea(null,10,10,TextArea.SCROLLBARS_BOTH);
jtf.setText("http://www.baidu.com");
jb=new JButton("获取网址信息");
jb.addActionListener(new ActionListener()

public static void main(String args[])
{
GetUrlInfo getUrlInfo=new GetUrlInfo();
System.out.println(Info.inputLine);
try
{
URL url=new URL(jtf.getText());
DataInputStream inputStr;
inputStr=new DataInputStream(url.openStream());
String inputLine;
while((inputLine=inputStr.readLine())!=null)
{
System.out.println(inputLine);//inputLine是输出内容.在dos下输出,我希望它在TextArea中输出..
}

inputStr.close();
}
catch(MalformedURLException e)
{
System.out.println("Error");
}
catch(IOException e)
{
System.out.println(e);
}
}
public static JTextField jtf;
private TextArea ta;
private JPanel jp;
private JButton jb;
private JLabel jl;
}

Answer 2

数组a=
1 2 3 4
2 3 4 5
3 4 5 6

for(int i=0;i<3;i++)
for(int j=0;j<4;j++)
输出 a[i][j]
