Object Oriented Programming (OOP)

 Object Oriented Programming (OOP)


    Object Oriented Programming is a programming concept that is based on Objects. There are many languages ​​that follow the OOP concept.

     Previously, code was written continuously in one block. Hundreds of lines of code were in one block. Then, if errors occur while running that program, it is difficult to find out which line and where the error occurs. Even if you go to update the program, it is difficult to find where you need to change because of a large block.

    For these reasons, programmers found a way to program the block into parts. The OOP concept was born as a result. Here, the block is broken into pieces based on objects.

Some Advantages of OOP programming

  • Troubleshooting is easier with the OOP language
  • Code Reusability
  • Productivity
  • Data Redundancy
  • Code Flexibility
  • Solving problems
  • Security


    There are 3 main blocks in OOP concept.
  • An object can be defined as a data field that has unique attributes and behavior.  
  • A class is a blueprint for creating objects.  
  • A method is a procedure associated with an object.  
  • Variables  are used to store information to be referenced and manipulated in a computer program.

Standards of OOP



In the OOP, we use a set of regulations to facilitate the future actions of the program. It is convenient for programmers. 

  • Class name - Class name should start with uppercase letter 
                class Car {
                    //code
                }
  • Method name - All characters are lowercase in method name and have parameters with in brackets.
                class  Car {
                    drive() {
                        //code
                    }
                }
  • Variable name - All characters are lowercase in variable name.
                                    class  Car {
                    drive() { 
                        int wheels ;
                    }
                }
  • Semi colon ( ; )- Used for donating line end.
                                    class   Car  {
                    drive()  { 
                        int wheels ;
                    }
                }
  • Open curly bracket ({ ) - Starting the block.
                                    class   Car  {
                    drive()  { 
                        int wheels;
                    }
                }
  • Closing curly bracket ( } ) - Ending the block.
                                    class   Car  {
                    drive()  { 
                        int wheels;
                    }
                }
  • Dot operator ( . ) - Used to call operations. 
                                    class   Car  {
                    drive()  { 
                        System . out . print("2023 Mortar Show");
                    }
                }
  • Comment ( // and /* .. */) - Used to create a comment.
                            class   Car  {
                drive()  { 
                   // this is one line comment
                   /*  this is multiline comment
                       this is multiline comment
                       this is multiline comment            
                   */
                }
            }

OOP Objects


Object is a combination of properties and behaviors. In OOP, all are objects (classes, methods, variables). 


 

OOP Class 


 OOP class sketch used to implement an object at the programming level. In simply word put, template to keep the things we need in order.

Class use properties as variables and behaviors as methods.

See you in the next blog to discuss about object generation, data types and parameters & arguments.

Sorting Algorithms - JAVA👽

 Sorting Algorithms - JAVA👽  Sorting algorithms are used to arrange data into a specific pattern (ascending or descending).We mainly discuss 5 patterns in this blog.  We can use any of this methods to sort an array. Selection sort Insertion sort Bubble sort Merge sort Quick sort  Selection sort ... Selection sort is well perform for small arrays and doesn't require extra temporary storage.  It uses selection method. It is poor to deal with huge list of items. It simple and easy to implement. It's time complexity is O(n^2) and space complexity is O(1). Here is the basic code for selection sort. for (int i=0; i< array.length-1; i++){             int curruntMinimum = i;             for (int curruntItem=i+1; curruntItem<array.length;curruntItem++){                 if(array[curruntItem] < array[curruntMinimum]){         ...

Object Oriented Programming - JAVA- class boundary, variable types, modifiers, java main method

Image
Object Oriented Programming - JAVA👽 There are certain aspects of Object Oriented Programming. So when we use OOP we need to know about those elements. In this blog, Let's discuss about class, variables, modifiers and methods & main method . Class.... A class is a blueprint that defines common variables and methods for objects of a particular type. A class has a boundary. Inside this boundary we only have the class, constructor and main method. Even if a method is in the class, we cannot take it to the class boundary. Variables.... Variables   are used to store information to be referenced and manipulated in a computer program. There are two variable types. Static variable Non - static variable Static variable The easiest way to find static variable is to find out if there is a static key ward.      ex :         static int i ; These can be accessed anywhere within the class. It can be accessed even without creating an object. Non - ...

Object Oriented Programming - JAVA- Method Overriding

Image
Object Oriented Programming - JAVA👽 Sometimes we have to fetch the same method name more than once. It is not possible in the programming process. But we can use method override to solve that error. So, in this blog we will discuss Method Overriding. Method overriding ... In a method inherited from a super class to a subclass, the process of changing the body is called as method overriding. So, To overriding the classes should inherit with one class to another class. Ex:   class Monkey{   void climb(){   sout ("Monkey climbs with their legs on jumping");   }    }   class Man extends Monkey{   void climb(){   sout ("Man climbs with using ladder");   }   } Here, above the subclass is the method of the superclass, and above that is the method of the subclass. That means, according to the example code,  The method of Man class is at the top The method of Monkey class is next The Man class is below the method o...
