[30%] Your paint method should use a loop to draw the position of the angry bird at each time
increment while the bird is in the air (y position >=0 ). Your code should honor the user's inputs
in this regard. You may assume no wind resistance. Important: This is not an animation; you'll be
drawing a fixed image. For example, the image at right statically depicts the motion of a circle
moving through an arc. [10%] Your loop should stop drawing the bird once it hits the ground or
the structure. It is okay if it draws the bird at a position that is outside of the window boundary

7. because it is too high or too far to the right.
ogistics and Hints - The starter code is just a .java file. To use it, you will need to create a new
BlueJ project then create a class named AngryBirds in the project. Finally, replace BlueJ's
default code for the AngryBirds class with the starter code. - Your graphics should be
recognizable but need not be particularly well drawn. They do not need to match the quality of
the actual Angry Birds game. - Since you will need to draw the angry bird in multiple locations,
you will probably want to create a method that can draws the bird at a specified x,y location. -
Below is pseudocode for drawing the arc of the bird's path. This code assumes Cartesian
coordinates (i.e., the y-axis goes up as normal). When painting the bird on the screen, you'll have
to convert the y-value to graphics coordinates (y-axis inverted). 0 Assign x and y-position to the
starting coordinate of the angry bird (the slingshot). o Assign time =0. o Main Loop: While bird
is in the air (y-position is above the ground): - Calculate x-position at the current time:
velocitycos(angle)time - Calculate y-position at the current time: velocity sin( angle) time 0.59.8
time 2 - Update the time by adding the timeInterval to it. - Draw the bird. Don't forget to invert
the y-axis. - If the bird has hit the structure (something you shall have to determine based on
your structure's position and design) then exit the loop. - The sin and cos functions are available
in the Math class. Note that these functions expect angles in radians (not degrees). - Your bird
position calculations should be using doubles, but you will need to convert these to ints to use as
coordinates for drawing. Use a type cast to do this conversion. - Put all your dialog windows in
the init() constructor and all your drawing in the paint() method.
