$1.$ Add to the House class a method named changeRoofColor that has a String parameter variable and changes the color of roof according to the argument passed in the parameter. $($Use changeColor, not setColor.$)$

$2.$ Add to the House class a method named changeWallColor that has a String parameter variable and changes the color of wall according to the argument passed in the parameter. $($Use changeColor, not setColor.$)$

$3.$ Add to the House class a method named changeWindowColor that has a String parameter variable and changes the color of window according to the argument passed in the parameter. $($Use changeColor, not setColor.$)$

$4.$ Add to the House class a method called moveHorizontal that takes an integer as input and moves the entire house that distance horizontally $($to the right for a positive integer and to the left for a negative integer$).$

This method needs to call the moveHorizontal methods for wall, roof, and window. You must move wall first because otherwise it will overwrite the move of window.

$5.$ Add to the House class a method called moveVertical similar to moveHorizontal that takes an integer as input and moves the entire house that distance vertically.

$6.$ Add to the House class a method called makeInvisible that makes the entire house invisible.

$7.$ Add to the House class a method called makeVisible that makes the entire house visible again.

The code in question these must be added to:

public class House

$\{$

private Square wall;

private Triangle roof;

private Square window;
