## InetAddress類
InetAddress類用于獲取網絡上的硬件資源，互聯網協議 (IP)地址，如ip地址、計算機名稱
~~~java
/*
* InetAddress類的常用方法
*/
public class Test01 {
public static void main(String[] args) throws UnknownHostException {
// 獲取本機的InetAddress實例,直接輸出的是本機名和ip地址
InetAddress address = InetAddress.getLocalHost();
System.out.println(address);
System.out.println("計算機名：" + address.getHostName() + " ip地址:"
+ address.getHostAddress());
byte[] bytes = address.getAddress();// 獲取字節數組形式的IP地址
System.out.println("字節數組形式的IP:" + Arrays.toString(bytes));
// 根據機器名和ip地址信息獲取InetAddress實例
InetAddress address2 = InetAddress.getByName("hj-PC");
}
}
