Question

Write an application program CarTester that does the following:

Creates three instances of Car, pass the following values to the constructor

first car object – 1HGBH42JXMN109186, true, 34675

second car object – JM1NA3535V0729833, false, 87211

third car object – JM1NA3535V0729833, false, 87211

Uses the equals method to determine if two Car objects are the same.  

Compare first Car object to second Car object, and second Car object to third Car object.

Print the following after comparing the Car objects:

If the cars are the same:

Found the car!

VIN: 1HGBH42JXMN109186

Anti-theft: Yes

Mileage: 34675

If the cars are different:

Cars are not the same!

First car:

VIN: 1HGBH42JXMN109186

Anti-theft: Yes

Mileage: 34675

Second car:

VIN: JM1NA3535V0729833

Anti-theft: No

Mileage: 87211

Explanation / Answer

Solution:

package com.nancy.chegg.qa;

public class Car {
  
   private String VIN;
   private boolean antiTheft;
   private int mileage;
  
   public Car(String vin, boolean antiTheft, int mileage) {
       super();
       this.VIN = vin;
       this.antiTheft = antiTheft;
       this.mileage = mileage;
   }

   public String getVIN() {
       return VIN;
   }

   public boolean isAntiTheft() {
       return antiTheft;
   }

   public int getMileage() {
       return mileage;
   }

   @Override
   public int hashCode() {
       final int prime = 31;
       int result = 1;
       result = prime * result + ((VIN == null) ? 0 : VIN.hashCode());
       result = prime * result + (antiTheft ? 1231 : 1237);
       result = prime * result + mileage;
       return result;
   }

   @Override
   public boolean equals(Object obj) {
       if (this == obj)
           return true;
       if (obj == null)
           return false;
       if (getClass() != obj.getClass())
           return false;
       Car other = (Car) obj;
       if (VIN == null) {
           if (other.VIN != null)
               return false;
       } else if (!VIN.equals(other.VIN))
           return false;
       if (antiTheft != other.antiTheft)
           return false;
       if (mileage != other.mileage)
           return false;
       return true;
   }
  

}
