Can you try to help me on this programming problem? Fig 3.1 and Fig 3.2 thank you...

3.2 Instance Variables, set Methods and get Methods 7I Typically, the apps you develop in this book will consist oftwo or more classes. If you become part of a development team in industry, you might work on apps that contain hundreds, or even thousands, of classes. 3.2 Instance Variables, set Methods and get Methods In this section, you'll create two classes Account (Fig. 3.1) and AccountTest (Fig. 3.2) Class AccountTest is an application class in which the main method will create and use an Account object to demonstrate class Account's capabilities 3.2.1 Account Class with an Instance Variable, a set Method and a get Method Different accounts typically have different names. For this reason, class Account (Fig. 3.1) contains a name instance wariable. A class's instance variables maintain data for each object (that is, each instance of the class. Later in the chapter we'll add an instance variable named balance so we can keep track of how much money is in the account. Class Account con- tains two method setName stores a name in an Account object and method getName obtains a name from an Account object.

Class Declaration The class declaration begins in line 5: public class Account The keyword public (which Chapter 8 explains in detail) is an access modifier. For now, we'll simply declare every dass public. Each public class declaration must be stored in a file having the same name as the class and ending with the java filename extension: otherwise
