如何在Java中通过恢复数据来设置int值

import java.io.FileInputStream;
import java.io.ObjectInputStream;

public class DataRecoveryExample {
    public static void main(String[] args) {
        try {
            FileInputStream fileIn = new FileInputStream("data.ser");
            ObjectInputStream in = new ObjectInputStream(fileIn);
            int recoveredValue = in.readInt();
            in.close();
            fileIn.close();
            System.out.println("Recovered value: " + recoveredValue);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
