In this example, we create a custom class, UserInfo which is shown in Code Sample. To make it serializable, it implements the Serializable interface.

Code Sample 3: UserInfo.java

mport java.io.*;

import java.util.*;

public class

UserInfo implements Serializable {

String name = null;

public UserInfo(String name) {

this.name = name;

}

public void printInfo() {

System.out.println("The name is: "+name);

}

}
