Key Points Of Object Oriented

Programming (OOP)

Object Oriented Programming:-

• It is a computer programming model based on object. We can use it in various programming languages to develop a program. 

Building Blocks of OOP

1. Object:-

            Object can be define as data field that has unique attributes and behaviors. 

            Objects can correspond to real-world objects or an abstract entity.

    2.Class:-

             Class is a sketch used to implement an object at the programming level.

            And also we an define class as "A template that can keep the things what we need".

  3.Method:-

            A method in OOP is a block of code that, when called, performs specific actions mentioned in it. 

  4.Variable:-

        Variables are containers for storing data values. In Java, there are different types of variables, for example:

                                              int

                                              double

OOP Standard

               Coding standards help in the development of software programs that are less complex and thereby reduce the errors.

               Object-Oriented Programming (OOP) standards  are used for several reasons,

1. Modularity and Reusability
2. Ease of Maintenance
3. Code Readability and Understandability

• Open and closing curly bracket-
• We use "{}" syntax for this.
• We use this to denote blocks of code or to define the scope of a class, method, or other code structures.

• Semi Colon-
• We use ";" syntax for this.
• It is used as a statement terminator. It indicates the end of a statement or a complete command.

• Dot Operator-
• We use "." syntax for this.
•  It is used as an operator to access members (attributes or methods) of an object or a class. The dot notation is crucial for interacting with objects and invoking their behaviors. 

• Class- 
• First letter should be in uppercase.
• Ex-  public class MyClass {}

• Variable-   
• Variables are containers for storing data values
• All characters should be in lowercase.
• Ex- 

                             public class MyClass

              {

                    int  number;

                    char letter;

              }

                                                

• Methods- 
• All characters should be in lower case and with parameters.
• Ex-

              public class MyClass

              {

                int  number;

                char letter;

               static void myMethod()

               {

               }

              }
