Introduction and Explanation of language purpose:
Java is the language best chosen for the banking purposes as it is true object oriented language and it can provide the best features with oop’s concepts ,it is not the 100 % object oriented language but it is true object oriented language and provided the best features and coding language over c and c++ and according to the specifications and competency I prefer the language java so to begin with I will first introduce the object oriented language and then I will discuss about java
Object Oriented languages : Object oriented languages are basically defines the concept of classes and objects and it deals with following properties if any language follows the following properties then it is known to be the object oriented language
I. Classes->if in any program everything is defined inside the class then it said to be following the feature of object oriented language as class is defined as the container for the data members(variables)and member functions(functions )and the keyword for defining class is ‘class’
II. Objects->Object is defined as the instance of the class as when class is defined no memory is allocated to the data members and member functions but when particular class is instantiated then the memory is allocated to the members of the class,In java we can define the object for any particular class as :’class name object name =new class name () ;’
III. Inheritance->Inheritance is the concept defined for the object oriented language which says that if any particular class is derived for the parent class and can access all the features of the parent class then there is inheritance exist between those two classes.
IV. Encapsulation->The wrapping up of data into a single unit is known as the Encapsulation ,and in Object oriented language we wrap up all data inside the class then it is known as the concept of Encapsulation
V)Abstraction ->showing only essential features without including the background details is known as the Data Abstraction. To give an example of abstraction we will create one superclass called Employee and two subclasses –  Contractor and FullTimeEmployee. Both subclasses have common properties to share, like the name of the employee and the the amount of money the person will be paid per hour. There is one major difference between contractors and full-time employees – the tyme they work for the company. Full-time employees work constantly 8 hours per day and the working time of contractors may vary.
Polymorphism -> polymorphism defines as to exist in different forms. In simple words, polymorphism is the ability of a function or message to be displayed in many forms or more than one form.
1. Real life consideration of polymorphism, suppose there is a person at same time can have different characteristic. Like a man at a same time is a father, a husband, an employee. So same person can exist in many forms in same time this is called polymorphism.
II. Data Hiding ->Using Object oriented language we can hide the data using the access specifiers like if we do not want our class data members to be accessed by other classes member functions then we can use private Access Specifiers and if we want our data members to be accessed by all other classes then we can use the public Access specifiers, and there another specifier available is protected which says that there will be accessibility of the data members within the derived class. So according to our requirement we can us the access specifier and can hide our data whenever required.
III. Message Passing-> In object oriented language we can also pass the message form one class to another using the objects and can make two or more classes communicate with each other.
OOP’s concepts can be shown graphically as:
JAVA:
JAVA is a true object-oriented programming (OOP) language, java is an object-oriented programming language developed by James Gosling and colleagues at Sun Microsystems in the early 1990s. Unlike conventional languages which are generally designed either to be compiled to native (machine) code, or to be interpreted from source code at runtime, Java is intended to be compiled to a bytecode, which is then run (generally using JIT compilation) by a Java Virtual Machine.
The language itself borrows much syntax from C and C++ but has a simpler object model and fewer low-level facilities. Java is only distantly related to JavaScript, though they have similar names and share a C-like syntax.
It follows the concept of Object oriented language and also basic features of c and c++ language hence it is easy to implement and easy to understand also hence I have chosen this language for banking purposes as whenever I want to use the concept of classes I can use that and whenever I want to use the simple syntax of functions then I can choose that also hence it will be very easy for me to implement the code using java
Java was started as a project called "Oak" by James Gosling in June 1991. Gosling's goals were to implement a virtual machine and a language that had a familiar C-like notation but with greater uniformity and simplicity than C/C++. The first public implementation was Java 1.0 in 1995. It made the promise of "Write Once, Run Anywhere", with free runtimes on popular platforms. It was fairly secure and its security was configurable, allowing for network and file access to be limited. The major web browsers soon incorporated it into their standard configurations in a secure "applet" configuration. popular quickly. New versions for large and small platforms (J2EE and J2ME) soon were designed with the advent of "Java 2". Sun has not announced any plans for a "Java 3".
JAVA also follows the concept of modularity as we can make functions also and we can also make the classes also hence modularity is achieved in this as it will be very helpful in designing the code and understanding it.
Java program development requires a Java software development kit ( SDK ) that typically includes a compiler, interpreter, documentation generator and other tools used to produce a complete application. 
Development time may be accelerated through the use of integrated development environments ( IDE ) - such as JBuilder, Netbeans, Eclipse or JCreator. IDEs facilitate the development of GUIs, which include buttons, text boxes, panels, frames, scrollbars and other objects via drag-and-drop and point-and-click actions.
Java applets run in a Web browser with Java Virtual Machine (JVM), which translates Java byte...
