TextField中的MAC地址

您好，我正在尝试创建一个GUI，并使用一个简单的按钮来刷新3个文本框中的信息。TextField中的MAC地址

IP地址主机名 MAC地址

领域的

上面我有前2分选他们的工作，但我不能工作，如何得到最后一个工作。

在我的GUI上，文本字段不包含代码，我使用按钮的代码来设置这些字段中的文本。

代码如下。

我无法揣摩出我与这个脚麻任何帮助在这一阶段是极大的赞赏，因为它是采取了很多的时间才能完成。

这段代码是为了获取我机器的本地，IP，Mac和主机名。

感谢您的任何帮助。

什么问题？ – Chiron

你的代码不完整，你的问题不清楚 – Reimeus

太棒了！它看起来像JBuidler生成的GUI。我出去了，对不起。 – Chiron

在Java 6及以上，你可以使用这种方法（和commons codec） - 替换这两行（从你的问题） -

byte[] mac = network.getHardwareAddress(); 
jTextField3.setText(.getHardwareAddress());

与这些线 -

Enumeration<NetworkInterface> nics = NetworkInterface 
     .getNetworkInterfaces(); // to actually make this work 
byte[] mac = null; 
while (nics.hasMoreElements()) { 
    NetworkInterface ni = nics.nextElement(); 
    if (ni != null && ni.getHardwareAddress() != null) { // Be sure. 
    mac = ni.getHardwareAddress(); 
    break; 
    } 
} 
// https://commons.apache.org/proper/commons-codec/javadocs/api-release/org/apache/commons/codec/binary/Hex.html 
if (mac != null) { 
    jTextField3.setText(Hex.encodeHexString(mac)); 
}

它在我的机器上工作。

感谢您的信息，但我仍然不确定如何实现此目的？然而，我确实有另一个项目，它抓住了IP，MAC和主机名，只是在没有GUI的输出中显示它。是否有可能从单独的项目输出中拖动信息，并在我的文本框中设置文本，这会更容易还是使事情更复杂？如果它更容易，我可以编辑我的帖子以显示我的其他项目的代码。 – user3080543

@ user3080543编辑我的回答，但是，我正在替换你的两行'byte [] mac = network.getHardwareAddress（）; jTextField3.setText（.getHardwareAddress（））;'我测试了它。 –
