It is highly advised that you build your work and knowledge upon the last labwork. You can watch the small video demo on WebOnline to get a better understanding. In additional to what we did in Lab3 you are going to; • Add a control panel. • Add two buttons to the panel called "Smaller" and "Bigger". • Menubar of this program should have an item called "Set Default"which will reset the values of x, y, dx and dy to the values they had initially. • Modify the action listener according to the buttons and menu item. • Set the title to "Mickey" in the constructor and add your WindowListener. • Modify your paint method to draw 3 ovals which makes up Mickey Mouse silhouette. Smaller ovals have half the radius of the big oval. • The center of the circle is determined by the variables x and y, and the radius of circles should be dependent on dx and dy (which are equal since we are using circles). •…//Movie.java import java.util.Arrays; public class Movie { private String movieName; private int numMinutes; private boolean isKidFriendly; private int numCastMembers; private String[] castMembers; // default constructorpublic Movie() { movieName = "Flick"; numMinutes = 0; isKidFriendly = false; numCastMembers = 0; castMembers = new String[10]; } // overloaded parameterized constructorpublic Movie(String movieName, int numMinutes, boolean isKidFriendly, String[] castMembers) { this.movieName = movieName; this.numMinutes = numMinutes; this.isKidFriendly = isKidFriendly; //numCastMember is set to array lengththis.numCastMembers = castMembers.length; this.castMembers = castMembers; } public String getMovieName() { return this.movieName; } public int getNumMinutes() { return this.numMinutes; } public boolean getIsKidFriendly() { return this.isKidFriendly; } public boolean isKidFriendly() { return this.isKidFriendly; } public int getNumCastMembers() { return this.numCastMembers; } public…
