Object Oriented Programming - JAVA - Method Overriding - Super keyword

 

Object Oriented Programming - JAVA 👽

Do you know about method overriding? 

We can't run super class method in method overriding with out special keyword "Super".
Super keyword is used to call the constructor of parent class from child class and refer to the things in  the super class.

Ex :
   class Father{
        Father() {
             sout ("Father of a child");
        }
   } 
   class Son extends Father{
        Son() {
            Super();
        }
   } 
   class Test{
        psvm {
             Son s = new Son();
        }
   }

The  'S' in the Super keyword is always capital.
We can access the super class's constructor, methods & variables with the Super keyword.
  • Super () ; 
            Used to call constructor of parent class.
  • Super.methodName () ; 
            Used to call mathods of parent class.
  • Super.variableName ;
            Used to call variables of parent class.

Let's meet in the next blog to discuss about "How to inherit classes" .

Application Programming Interface (API)

 Application Programming Interface (API) 👽 In the modern world, APIs are mostly used for software development. It act as a bridge, It acts as a bridge, enabling developers to access specific features or data from another application, service, or platform without exposing its internal workings. What is an API ?      An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines how requests and responses should be made between systems, enabling developers to integrate functionalities from one application into another.     An API is like a waiter in a restaurant. If you (the client) tell the waiter (the API) what you want from the kitchen (the software or service). The waiter then brings your request to the kitchen and brings the result back to you. It helps different software systems talk to each other and share information. Why are APIs important? Effici...

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 - ...
