今天在寫 Java 的時候，遇到問題跑去問 TonyQ 兄，他丟了一個網址給我，剛剛測試過了，還漫好用的,紀錄一下
模擬 ping 的實現
import java.io.*;
import java.net.*;
public class PseudoPing {
public static void main(String args[]) {
try {
InetAddress address = InetAddress.getByName(args[0]);
System.out.println(address.isReachable(5000));
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
import java.net.*;
public class PseudoPing {
public static void main(String args[]) {
try {
InetAddress address = InetAddress.getByName(args[0]);
System.out.println(address.isReachable(5000));
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
}
模擬 telnet 的實現
Socket server = null;
try {
server = new Socket();
InetSocketAddress address = new InetSocketAddress("192.168.0.201",8899);
server.connect(address, 5000);
} catch (UnknownHostException e) {
System.out.println("telnet失败");
} catch (IOException e){
System.out.println("telnet失败");
}finally{
if(server!=null)
try {
server.close();
} catch (IOException e) {
}
}
try {
server = new Socket();
InetSocketAddress address = new InetSocketAddress("192.168.0.201",8899);
server.connect(address, 5000);
} catch (UnknownHostException e) {
System.out.println("telnet失败");
} catch (IOException e){
System.out.println("telnet失败");
}finally{
if(server!=null)
try {
server.close();
} catch (IOException e) {
}
}
