If a class is serializable but its superclass in not , what will be the state of the instance variables inherited from super class after deserialization?

The values of the instance variables inherited from superclass will be reset to the values they were given during the original construction of the object as the non-serializable super-class constructor will run.

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;

public class SubSerialSuperNotSerial {

    public static void main(String [] args) {

        ChildSerializable c = new ChildSerializable();
        System.out.println("Before : - " + c.noOfWheels + " "+ c.color);
        try {
        FileOutputStream fs = new FileOutputStream("superNotSerail.ser");
        ObjectOutputStream os = new ObjectOutputStream(fs);
        os.writeObject(c);
        os.close();
        } catch (Exception e) { e.printStackTrace(); }

        try {
        FileInputStream fis = new FileInputStream("superNotSerail.ser");
        ObjectInputStream ois = new ObjectInputStream(fis);
        c = (ChildSerializable) ois.readObject();
        ois.close();
        } catch (Exception e) { e.printStackTrace(); }
        System.out.println("After :- " + c.noOfWheels + " "+ c.color);
        }

}

 class ParentNonSerializable {
    int noOfWheels;
   
    ParentNonSerializable(){
        this.noOfWheels = 4;
    }
   
}


 class ChildSerializable extends ParentNonSerializable implements Serializable {
 
    private static final long serialVersionUID = 1L;
    String color;


    ChildSerializable() {
        this.noOfWheels = 8;
        this.color = "blue";
    }
}

Result on executing above code –
Before : - 8 blue
After :- 4 blue

The instance variable ‘noOfWheels’ is inherited from superclass which is not serializable. Therefore while restoring it the non-serializable superclass constructor runs and its value is set to 8 and is not same as the value saved during serialization which is 4.
