在Java中,枚舉值可以通過實現Serializable接口來進行序列化。具體步驟如下:
import java.io.Serializable;
public enum Color implements Serializable {
RED, GREEN, BLUE;
}
import java.io.FileOutputStream;
import java.io.ObjectOutputStream;
public class SerializationExample {
public static void main(String[] args) {
try {
Color color = Color.RED;
FileOutputStream fileOut = new FileOutputStream("color.ser");
ObjectOutputStream out = new ObjectOutputStream(fileOut);
out.writeObject(color);
out.close();
fileOut.close();
System.out.println("Serialized data is saved in color.ser");
} catch (Exception e) {
e.printStackTrace();
}
}
}
import java.io.FileInputStream;
import java.io.ObjectInputStream;
public class DeserializationExample {
public static void main(String[] args) {
try {
FileInputStream fileIn = new FileInputStream("color.ser");
ObjectInputStream in = new ObjectInputStream(fileIn);
Color color = (Color) in.readObject();
in.close();
fileIn.close();
System.out.println("Deserialized color: " + color);
} catch (Exception e) {
e.printStackTrace();
}
}
}
這樣就可以實現枚舉值的序列化和反序列化操作。需要注意的是,枚舉值在反序列化時必須是在同一個枚舉類中定義的,否則會拋出ClassCastException異常。
