Object-Oriented Programming (OOP)

Object-Oriented Programming (OOP)

1. Classes

   • Template to create objects Classification that dictates the objects' fields and methods
   • Syntax
     • *class className {          [class body]  }
   • Dictates if objects will have
     • Fields
       • A variable, defines characteristics and input parameters
         • Work as a general blueprint for future objects
     • Methods
       • Actions that objects will perform
         • Syntax
           • *returnType methodName(listOfArguments);
       • Main Method
         • Entry point for an application (only one class needs it)
   • A type of performer that will give common identification to objects

2. Objects

   • Represents real life entities under a defined class
   • Syntax Example
     • *Employee employee = new Employee();         employee.age = 24;         employee.salary = 50000;
   • Data Input from real world
     • Give identity to fields and methods for a specific case

3. THINKING PROCESS

   • 1) QUESTIONS TO ASK YOURSELF
     • Functional requirements?
     • World's Problem?
     • Non-functional requirements?
     • 2) Solution
       • Analysis
       • Design
       • Construction
