implements serializable使用

implements serializable是Java中的一个接口，用于标记一个类可以被序列化。当一个类实现了Serializable接口后，它的对象就可以被序列化成一个字节流，以便在网络上传输或者存储到本地磁盘上。同时，也可以将序列化后的字节流反序列化成原来的对象。这个接口没有任何方法需要实现，只是一个标记接口。

implements Serializable

The "implements Serializable" statement is used to indicate that a class in Java can be serialized, which means it can be converted into a stream of bytes that can be saved to a file or sent over a network. This allows the object to be reconstructed later, possibly on a different machine or at a different time, while preserving its state.

To implement serialization, a class needs to implement the Serializable interface, which is a marker interface with no methods. This means that the class only needs to declare that it implements Serializable, and the serialization mechanism will automatically handle the rest.

Here is an example of a class that implements Serializable:

public class Person implements Serializable {
  private String name;
  private int age;
  
  public Person(String name, int age) {
    this.name = name;
    this.age = age;
  }
  
  public String getName() {
    return name;
  }
  
  public int getAge() {
    return age;
  }
}

In this example, the Person class has two fields (name and age) and a constructor and two getter methods. By implementing Serializable, this class can now be serialized and deserialized using Java's built-in serialization mechanism.

implements serializable

"Serializable" 是 Java 程序设计语言中的一个接口，它允许一个对象的状态被保存到存储媒体上并在需要时可以重新读取。当一个类实现了 Serializable 接口后，它的对象就可以被序列化和反序列化。
