Using a Turtle from Exercise 23 and employing the incremental development steps, build a Java application that draws a house.

Reference Exercise 23: At the author’s website, you will find a Java package called galapagos. The galapagos package includes a Turtle class that is modeled after Seymour Papert’s logo. This Turtle has a pen, and when you move the Turtle, its pen will trace the movement. So by moving a Turtle object, you can draw many different kinds of geometric shapes. For example, this program commands a Turtle to draw a square:

import galapagos.*;

class Square {

public static void main( String[] arg ) {

Turtle turtle;

turtle = new Turtle( );

turtle.move( 50 ); //move 50 pixels

turtle.turn( 90 ); //turn 90 deg counterclockwise

turtle.move( 50 );

turtle.turn( 90 );

turtle.move( 50 );

turtle.turn( 90 );

turtle.move( 50 );

}

}

Write a program to draw a triangle. Read the documentation and see if you can find a way to draw the square in a different color and line thickness.
