InetAddress IP4=InetAddress.getByName("192.168.1.100");

Question

InetAddress IP4=InetAddress.getByName("192.168.1.100");
转换IP4=/192.168.1.100为什么多了个"/"?
应该怎样做？

Answer 1

ip4.getHostAddress();toString() 是 getHostName()/getHostAddress() 形式的。参考：import java.net.InetAddress;
import java.net.UnknownHostException;public class Test {
    
    public static void main(String[] args) throws UnknownHostException {
        InetAddress ip4 = InetAddress.getByName("community.csdn.net");
        System.out.println(ip4.toString());
    }
}
