在java中通过序列化获取多个对象
我想使用序列化从文件中获取Employee类的多个对象。在这里,我只得到一个对象,任何解决方案
package com.jbt;
import java.io.Serializable;
public class Employee implements Serializable
{
public String firstName;
public String lastName;
private static final long serialVersionUID = 5462223600l;
}
package com.jbt;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
public class SerializaitonClass {
public static void main(String[] args) {
Employee emp = new Employee();
emp.firstName = "Vivekanand";
emp.lastName = "Gautam";
try {
FileOutputStream fileOut = new FileOutputStream("./employee.txt");
ObjectOutputStream out = new ObjectOutputStream(fileOut);
out.writeObject(emp);
out.close();
fileOut.close();
System.out.printf("Serialized data is saved in ./employee.txt file");
} catch (IOException i) {
i.printStackTrace();
}
}
}
package com.jbt;
import java.io.*;
public class DeserializationClass {
public static void main(String[] args) {
Employee emp = null;
try {
FileInputStream fileIn = new FileInputStream("./employee.txt");
ObjectInputStream in = new ObjectInputStream(fileIn);
emp = (Employee) in.readObject();
in.close();
fileIn.close();
} catch (IOException i) {
i.printStackTrace();
return;
} catch (ClassNotFoundException c) {
System.out.println("Employee class not found");
c.printStackTrace();
return;
}
System.out.println("Deserializing Employee...");
System.out.println("First Name of Employee: " + emp.firstName);
System.out.println("Last Name of Employee: " + emp.lastName);
}
}
在反序列化类中,我如何在列表中获取多个对象?? 提前谢谢
# 1 楼答案
注意:您还可以序列化
List
并将其存储在文件中,然后对其进行反序列化。(添加列表为可序列化列表)# 2 楼答案
可以按如下方式序列化和反序列化对象数组:
