Java:inetaddress to String conversion

Question

我搜索了很多，但我找不到任何方法将inetaddress类型转换为字符串（可能是我的搜索不是那么好：S）。我必须将其转换为字符串类型，因为我必须在textarea中显示结果（gui组件）需要字符串类型。任何人都可以这样做？

Answer 1

Java API for InetAddress class has good methods for your needs, I see. Try these methods. You can check out other property getters of InetAddress for your further requirements.

public static void main ( String [] args ) throws UnknownHostException
{
    // Instantiate your own InetAddress object.
    InetAddress address = InetAddress.getLocalHost(); 
    String hostIP = address.getHostAddress() ;
    String hostName = address.getHostName();
    System.out.println( "IP: " + hostIP + "\n" + "Name: " + hostName);
}

Answer 2

你试过InetAddress.toString（）方法吗？

Answer 3

Just call the InetAddress toString() method. Also, if you specifically want the host name, use getHostName. If you want a string representation of the IP address, use getHostAddress() .

sample :

InetAddress inet = InetAddress.getByName("193.125.22.1");
System.out.println(inet.toString());

Answer 4

What about

System.out.println(Inet4Address.getLocalHost().getHostAddress());

?
