1 用JAVA写一个服务程序,监听一个TCP端口,接受请求,进行处理并给出响应2 编写一个SHELL脚本,处理NETSTAT的输出(随便选择1,2个参数进行输出)
解决方案 »
- java异常处理

- Set里的元素是不能重复的,那么用什么方法来区分重复与否呢?是用==还是equals()?它们有何区别?
- 如何用java调用windows的dll,例如msimg
- 正则表达式
第2个 你可以把netstat的输出重定向为脚本的输入,然后再处理,好像是这样的
netstat | shellscript
不过shell我就不怎么会写了
import java.io.*;class StreamGobbler extends Thread
{
InputStream is;
String type;
StreamGobbler(InputStream is, String type)
{
this.is = is;
this.type = type;
}
public void run()
{
try
{
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line=null;
while ( (line = br.readLine()) != null)
System.out.println(type + ">" + line);
} catch (IOException ioe)
{
ioe.printStackTrace();
}
}
}public class GoodWindowsExec
{
public static void main(String args[])
{
if (args.length < 1)
{
System.out.println("USAGE: java GoodWindowsExec <cmd>");
System.exit(1);
}
try
{
String osName = System.getProperty("os.name" );
String[] cmd = new String[3];
System.out.println( osName);
if( osName.equals( "Windows 2000" ) )
{

}
Runtime rt = Runtime.getRuntime();
System.out.println("Execing " + cmd[0] + " " + cmd[1]
+ " " + cmd[2]);
Process proc = rt.exec(cmd);
// any error message?
StreamGobbler errorGobbler = new
StreamGobbler(proc.getErrorStream(), "ERROR");
// any output?
StreamGobbler outputGobbler = new
StreamGobbler(proc.getInputStream(), "OUTPUT");
// kick them off
errorGobbler.start();
outputGobbler.start();
// any error???
int exitVal = proc.waitFor();
System.out.println("ExitValue: " + exitVal);
} catch (Throwable t)
{
t.printStackTrace();
}
}
}
第一题!
ServerSocket ss = new ServerSocket(port);
Socket s = null;
//进行监听
if (ss!=null){
try{
s = ss.accept();
} catch (Exception e){}
}
//写端口
PrintStream pw = new PrintStream(s.getOutputStream());
pw.print("hello");
