An application can use this object to execute code automatically at regular time intervals.
Timer
A problem can be solved recursively if it can be broken down into successive smaller problems that are identical to the overall problem.
True
If you want to make sure that an applet is compatible with all Java-enabled browsers, use AWT components instead of Swing.
True
Instead of displaying its own window, an applet appears in the browser's window.
True
Recursion is never absolutely required to solve a problem.
True
There is no static main method needed to create an instance of the applet class because the browser creates an instance of the class automatically.
True
When you update the data used to draw shapes on a component, you must call the repaint method to force a call to the paint or paintComponent methods.
True

7
The Towers of Hanoi is a mathematical game that is often used in computer science textbooks to illustrate the power of recursion.
True

Once you create a mouse listener class, you can register it with a component using this method, which is inherited from the Component class.
addMouseListener
An applet class inherits from this class.
JApplet
The ________ is at least one case in which a problem can be solved without recursion.
base case
An applet class has a method named ________ that performs the same operations as a constructor.
init
Which of the following problems can be solved recursively?

False
A recursive method can have no more than one base case.
False
Applets are important because they can be used to extend the capabilities of a stand-alone Java application.
False
In HTML, the <h1></h1> tag marks a document's head section, whereas the <head></head> tag marks a header, which is large bold text.
False
Whereas a recursive algorithm might result in faster execution time, the programmer might be able to design an iterative algorithm faster.
False

applet
A method that calls itself is a ________ method.
recursive
