4. (10 points) Left Initial Position Right 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. Declare two instance variables: current Position and direction Provide a constructor public Bug (int initialPosition) and accessor/mutator methods public int getPosition() public void move() public void turn() Sample code for testing: Bug bugsy = new Bug (10); //starts at initial position 10 bugsy.move(); // Now the position is 11 bugsy.move(); // Now the position is 12 System.out.println (bugsy.getPosition()); //should print 12 bugsy.turn(); // Now the direction has changed bugsy.move(); // Now the position is 11 System.out.println (bugsy.getPosition() ); //should print 11
