Java如何獲取本地計(jì)算機(jī)的IP地址和主機(jī)名

可以使用 InetAddress.getLocalHost()，代碼如下：

java中如何獲得計(jì)算機(jī)的信息。

System.getProperties()

返回的是Properties

Properties 類表示了一個(gè)持久的屬性集

以下的代碼就可以把Properties的內(nèi)容讀出來(lái)

Properties props = new Properties();

try {

InputStream in = new BufferedInputStream (new FileInputStream(filePath));

props.load(in);

Enumeration en = props.propertyNames();

while (en.hasMoreElements()) {

String key = (String) en.nextElement();

String Property = props.getProperty (key);

System.out.println(key+Property);

}

} catch (Exception e) {

e.printStackTrace();

}

對(duì)于補(bǔ)充的回答：

java不能直接得到樓主需要的信息，但是可以采用JNI,即調(diào)用C程序，讓C得到這些信息
