两种办法:

1) 在原有方法里加设置到textfield的命令

public static void ipaddress()

{

try{

InetAddress inet = InetAddress.getLocalHost();

System.out.println(inet.getHostAddress());

text1.setText(inet.getHostAddress());//new added

}

catch(UnknownHostException e){

System.err.println("UnknownHostException" + e.getMessage());

}

}

2) 方法改返回值.

public static String ipaddress()

{

String ret = null;

try{

InetAddress inet = InetAddress.getLocalHost();

ret=inet.getHostAddress();

System.out.println(ret);

}

catch(UnknownHostException e){

System.err.println("UnknownHostException" + e.getMessage());

}

return ret;

}

然后在调用此方法的后面,加

text1.setText(inet.getHostAddress());

取消
