1. Java根据MAC地址获取IP地址的方法:
Java中可以使用InetAddress类来获取网络上的IP地址。但是,InetAddress类并没有提供直接的方法来获取MAC地址。在Java中获取MAC地址需要通过操作系统提供的API来实现。下面是一种获取MAC地址的方法:
```java
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
import java.util.Enumeration;
public class MacUtil {
public static String getMacAddress(String ipAddress) throws UnknownHostException, SocketException {
InetAddress inetAddress = InetAddress.getByName(ipAddress);
NetworkInterface network = NetworkInterface.getByInetAddress(inetAddress);
byte[] mac = network.getHardwareAddress();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
}
return sb.toString();
}
}
```
2. Java根据本地IP获取MAC地址的方法:
Java中同样可以使用InetAddress类来获取本地IP地址。获取本地MAC地址同样需要通过操作系统提供的API来实现。下面是一种获取本地MAC地址的方法:
```java
import java.net.InetAddress;
import java.net.NetworkInterface;
import java.net.SocketException;
import java.net.UnknownHostException;
import java.util.Enumeration;
public class MacUtil {
public static String getMacAddress() throws UnknownHostException, SocketException {
InetAddress inetAddress = InetAddress.getLocalHost();
NetworkInterface network = NetworkInterface.getByInetAddress(inetAddress);
byte[] mac = network.getHardwareAddress();
StringBuilder sb = new StringBuilder();
for (int i = 0; i < mac.length; i++) {
sb.append(String.format("%02X%s", mac[i], (i < mac.length - 1) ? "-" : ""));
}
return sb.toString();
}
}
```
