Question

On the Turtle class I need to make a method so turtle 0 and turtle 2 to "kiss" or touch their heads. Everything that can be use is in the SimpleTurtle link. https://www2.cs.uic.edu/~i101/doc/SimpleTurtle.html

public void turtleTricks()
{
int worldWidth = 800;
int worldHeight = 600;
Random random = new Random();
World earth = new World(worldWidth, worldHeight );//Make a big world for turtles.
  
Turtle[] turtles = new Turtle[5];
int xLocation, yLocation, angle;
for ( int i = 0; i < turtles.length; i++ )
{
xLocation = random.nextInt( worldWidth - 100 );
yLocation = random.nextInt( worldHeight - 100 );
angle = random.nextInt( 360 );
turtles[i] = new Turtle( earth );
turtles[i].penUp(); //pick up the pen just to put each into a different location
turtles[i].moveTo(xLocation + 50, yLocation + 50 );
//subtracted 100 from each dimension, then add 50 to make sure no turtle is placed too
//close to an edge.
turtles[i].turn( angle ); //Have them all start facing different directions.
turtles[i].penDown(); //Ready to draw.
}
  
  
  
//testing starts here
//turtles[0].drawSquare();
//turtles[1].drawSquare( 200 );
//turtles[2].drawRectangle( 50, 200 );
//turtles[3].drawRegularPolygon( 8, 100 );
//turtles[4].drawRegularPolygon( 5, 100 );

turtles[0].kiss( turtles[2]);
  
}//end turtleTricks

}

}
  

} // end of class Turtle, put all new methods before this
