Write a class Bug that models a bug moving along a horizontal line. The bug moves either to the right or left. Initially, the bug moves to the right, but it can turn to change its direction. In each move, its position changes by one unit in the current direction. Provide a constructor

Following are the constructor to the given code:

Bug(int position) //defining a constructor that defines a integer parameters

{

       this.position = position;//use this key word to hold parameter value

       right = true;//defining a variable right that hold a boolean value

   }

Explanation:

In this code, a constructor is declared that defines integer parameters with it, Inside the constructor, this keyword is used to holds the "position" parameter value and defines a boolean variable "right" that holds a boolean value.

Full program:

public class Bug //declaring a class Bug

{

   private int position;//declaring integer variable position

   private boolean right;//declaring boolean variable

   public Bug(int position) //defining a parameterized constructor

   {

       this.position = position;//use this to hold position value

       right = true;//holding boolean value

   }

   public void turn() //defining a method turn

   {

       right = !right;//holding value

   }

   public void move() //defining method move

   {

       if(right)//use if to check boolean value

       {

           position++;//incrementing position value

       }  

       else//else block

       {

           position--;//decreasing position value

       }

   }

   public int getPosition()//defining method getPosition  

   {

       return position;//return position value

   }

   public static void main(String[] args) //main method

   {

       Bug bug = new Bug(10);//creating class object

       System.out.println("Expected = 10, Actual = " + bug.getPosition());//calling method with printing value

       bug.move();//calling method

       System.out.println("Expected = 11, Actual = " + bug.getPosition());//calling method with printing value

       bug.move();//calling method

       bug.move();//calling method

       bug.move();//calling method

       System.out.println("Expected = 14, Actual = " + bug.getPosition());//calling method with printing value

       bug.turn();//calling method

       bug.move();//calling method

       bug.move();//calling method

       System.out.println("Expected = 12, Actual = " + bug.getPosition());//calling method with printing value

       bug.turn();//calling method

       bug.move();//calling method

       System.out.println("Expected = 13, Actual = " + bug.getPosition());//calling method with printing value

   }

}
