Why is the output showing "Car@1eb44e46, Car@1c4af82c, Chevy, Camaro, 2021, Chevy, Camaro, 2021" instead of "Car@1eb44e46, Car@1c4af82c, Chevy, Camaro, 2021, Ford, Mustang, 2022"?

class Car {
   private String make;
   private String model;
   private int year;
   Car (String make, String model, int year)
   {
       this.setMake(make);
       this.setModel(model);
       this.setYear(year);

   }
   public String getModel(){

       this.make = make;
   }
