Thread: Unable to Serialize arrayList of Object even after implementing the class

So I was trying to serialize an arraylist of object that hold names but it gives me unserializable error although implemented it in both classes too after it failed to run when i implemented it the main class only.
I will paste the code and the error message
main class

package serial;
 
import java.io.BufferedOutputStream;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import java.util.ArrayList;
import java.util.Scanner;
 
public class main implements Serializable {
 
 
	public static void main(String[] args) throws IOException {
		Scanner input = new Scanner(System.in);
		ArrayList<names> name= new ArrayList<names>();
 
 
		{
			name.add(new names());
			File File = new File("C:\\Users\\kuchuk borom debbarm\\Desktop\\test\\name.txt");
			if(File.exists()) {
 
			}
			else {
				File.createNewFile();
			}
			ObjectOutputStream fileF= new ObjectOutputStream(new FileOutputStream(File));
			fileF.writeObject(name); //this is where the code fails
			fileF.close();
			}
		}
 
}

secondary class

package serial;
 
import java.io.Serializable;
import java.util.Scanner;
 
public class names implements Serializable {
	Scanner input=new Scanner(System.in);
public names() {
	System.out.println("uy");
String names=input.nextLine();
}
}

here is the error

uy
kuku

Exception in thread "main" java.io.NotSerializableException: java.util.Scanner

Look at the API doc for this class: java.io.NotSerializableException
It explains the problem.

Note: Java naming conventions says that class names should begin with an UPPERCASE letter: Names and Main
