Question

Write a class called Taxicab that has three int fields (data members) to store its current x- and y-coordinates and the total distance it has driven so far (the actual distance driven by the Taxicab, not the Euclidean distance from it's starting point). The class should have a constructor that takes two parameters and uses them to initialize the coordinates, and also initializes the distance traveled to zero. The class should have a default constructor that sets all three fields to zero. The data members of this class do not need to be set after they are initialized, so this class doesn't need any set methods - therefore the constructors will directly assign values to the data members instead of calling set methods to do it. The class should have a get method for each data member. It should have a method called moveX that takes an int parameter that tells how far the Taxicab should shift left or right. It should have a method called moveY that takes an int parameter that tells how far the Taxicab should shift up or down. For example, the Taxicab class might be used as follows:

Hey, below is your class TaxiCab, i have mentioned comments where-ever necessary, also i have included TestTaxiCab class to test TaxiCab class.

TaxiCab.java

public class Taxicab {

private int currentX;

private int currentY;

private int totalDistance;

//Default constructor that sets all three fields to zero

public Taxicab() {

this.currentX = 0;

this.currentY = 0;

this.totalDistance = 0;

}

// Constructor which sets all current values of X and Y and also total distance as 0.

public Taxicab(int currentX, int currentY) {

this.currentX = currentX;

this.currentY = currentY;

this.totalDistance = 0;

}

public int getCurrentX() {

return currentX;

}

public int getCurrentY() {

return currentY;

}

public int getTotalDistance() {

return totalDistance;

}

public void moveX(int x) {

this.currentX = this.currentX + x;

this.totalDistance = this.totalDistance + Math.abs(x);

}

public void moveY(int y) {

this.currentY = this.currentY + y;

this.totalDistance = this.totalDistance + Math.abs(y); // add absolute value of y to total distance covered, as distance covered is independent of the direction of taxi.

}

}

TestTaxiCab.java

public class TestTaxiCab {

public static void main(String[] args) {

Taxicab taxicab = new Taxicab();

taxicab.moveX(14);

taxicab.moveX(-16);

taxicab.moveY(1);

taxicab.moveX(8);

taxicab.moveX(3);

taxicab.moveY(-6);

System.out.println(taxicab.getCurrentX());

System.out.println(taxicab.getCurrentY());

System.out.println(taxicab.getTotalDistance());

}

}

output

Thanks!!
