Question

1. Implement the Vehicle class.

 Add the following private instance variables to the Accoun class:

• An instance variable called wheelsCount of type int

• An instance variable called vType of type String

• An instance variable called isTruck of type boolean .

 Add getters and setters for the three instance variables

 Add the following methods to the Account class:

• A void method called initialize that takes a parameter of type int, a String,and one double and uses those arguments to set the values of the WheelsCount VType,and isTruck instance variables.

• A void method called display that displays the vehicle information

• A boolean method called equals with one parameter of type Vehicle.This method must return true if all instance variables of the given objects equal to the instance variables of the current object (this object).

 In the main method of your main class, create two Vehicle objects and perform the following:

• Initialize the first and second objects with your own parameter values.

• Display both vehicles • Use the == to compare the two vehicle objects and display the result.

• Use the equals method for the first object, compare it with the second vehicle as the parameter to the method and display the result.

Run the main program to see if the tests were successful.

• Here is a sample output of the program.

First Vehicle:

Vehicle Type: Ford F150

Wheels Count: 4

is Truck: true

Second Vehicle:

Vehicle Type: Ford F150

Wheels Count: 4

is Truck: true

v1 is NOT equal to v2 using ==

v1 is equal to v2 using equals method

Answer 1

Note:
If you are a beginner I will help you in executing the code.
Could you plz go through this code and let me know if u need any changes in this.Thank You

// Vehicle.java

       this.wheelsCount = noOfWheels;
       this.vType = vType;
       this.isTruck = isTruck;
   }

   public void display() {
       System.out.println("Vehicle Type :" + vType);
       System.out.println("Wheels Count :" + wheelsCount);
       System.out.println("is Truck :" + isTruck);
   }

   // This method will check whether the two vehicle class objects are equal or not
   public boolean equals(Vehicle v) {
       if (vType.equalsIgnoreCase(v.getvType())
               && wheelsCount == v.getWheelsCount() && isTruck == v.isTruck()) {
           return true;
       } else {
           return false;
       }
   }

// Tester.java

public class Tester {

       Vehicle v1 = new Vehicle();
       v1.initialize(4, "Ford F150", true);

       System.out.println("First Vehicle:");

       if (v1 == v2) {

           System.out.println("v1 is NOT equal to v2 using ==");
       }

       if (v1.equals(v2)) {
           System.out.println("v1 is equal to v2 using equals method");
       } else {
