Why coding standards for java?


 Standards in java code, we can mention it also as coding conversions or style guidelines. Those are essential in many ways, but in the first place it’s for identity purpose. Programmers follow those regulations for give code to quality, readability, maintainability and collaboration aspects of Java code.


Here are some key reasons why standards in java code are important.


1.Readability

Coding standards ensure that code is written in a consistent manner throughout a project. This consistency makes it easier for developers to read and understand the code.


 

2.Maintainability

When developers follow a consistent style, it becomes simpler to identify and fix bugs.


 

3.Collaboration

In a collaboration development environment ,multiple developers work on same project .Coding standards facilitate collaboration by providing a shared set of guidelines, ensuring that team members can understand each other’s code easily.

 

 

4. Industry Standards and Conventions

        Following coding standards align codebase with industry and communication conventions. This makes it easier for other developers, Mainly those are not familiar with code other’s specific project ,to understand and contribute to the code.


Coding Standards for Classes: 

 

  • Usually meaningful and descriptive names use for classes and name represent the purpose or role of the class.

  • Use capital letter for first letter of class. Further, CamelCase or we can tell it as  PascalCase. It means that capitalize the first letter of each word.

Eg: String, StringBuffer, Dog


Coding Standards for Variables: 

  • Usually variable name should be lowercase letter.
  •  If it contains multiple word than every inner word should start with uppercase (CamelCase).

Eg: name, age. mobileNumber


Coding Standards for Methods: 

  • Usually method name should either be verb or verb noun combination.
  • starting with lower letter and If it contains multiple word than every inner word should start with uppercase.

Eg: print(), sleep(), setSalary()

Java Object and Classes

Java  Object


In Java, an object is a concept used to represent  real-world entities in a  program. Objects are instances of classes, which serve as blueprints or templates defining the properties and behaviors common to a group of objects.

In simply we can tell object is process or the action.


public class Car {

    // Attributes

    String make;

    String model;

 

    // Methods

    void startEngine() {

        // Method implementation

    }

}


Java Class

 

In Java, a class is a block of object-oriented programming (OOP) helps to arrange the things we need to.  It serves as a blueprint or template for implements objects.  A class defines the properties and behaviors (methods) that objects of that type will have.


public class MyClass {

    // Class members (fields and methods) go here

}

Linked List Data Structures

Image
  Linked List Previous and next pointers are the connectors that connect the nodes. In one node previous pointer become the   next node’s previous pointer. If we add node to the Linked List we can add it using the next pointer, and if we want to remove also we can remove it along with the node’s next pointer.   A linked list is a linear collection of elements, called nodes, where each node holds a reference to the next node in the sequence. Unlike arrays, linked list elements are not stored in contiguous memory locations. Instead, each node contains data and a pointer/reference to the next node. Types of Linked Lists   1. Singly Linked Lists:    In a singly linked list, each node points to the next node in the sequence. The last node points to null, indicating the end of the list. Singly linked lists are simple to implement and memory-efficient.   2. Doubly Linked Lists:     In a doubly linked list, each node has pointers to b...

Java OOPC -Encapsulation

Image
Encapsulation In real life capsule is based for the concept Encapsulation, We use capsule for the protection and security of the medicine that inside the capsule from   of environmental conditions and other things because that conditions generated unhealthy components.   In here when it comes to object oriented concept Encapsulation is that data hiding, protection and security. Further this concept we use for the variables.   We talk about the GET and SET methods thought the concept encapsulation,   Getters and setters   For the better security we use access modifier ‘private’   ,because in private modifier only let the specific class accessing. So private variables can use outside of the specific method using GET and SET methods.   Indeed we use private keyword for data security purpose but in some time some specific reasons we need to use those outside of the class we define it previously, Because of this reason we use getter...

Java OOPC - Interface

Image
  Interface Interface is keyword use in Java .Instead of using ‘class’ keyword using ‘interface’ we can create interface. As the same way creating a class we can create interface also.   Interface is also a class, but interface is not a class it work same as a class. Difference between class and interface ,interface can not   create object because of that interface even can not create constructor, But after Java 8 we can use constructors.   We can not do multiple inheritance. means that we can not inherit   more than one super class from sub class. Using extends we can not do multiple inheritance. But using the implements we can do multiple inheritance. Implements what inheritance do using the interface. So the purpose of using the interface is do the multiple inheritance. As we know we can not create the objects to the interfaces but using the upcasting we can create objects. In here object generate side be the class indeedly,   then that cla...
