Java Programming

The Benefits of Using Java

Java is widely used because of the following benefits:

• Java is very easy to learn as the syntax is similar to the older programming languages C and C++

• It is platform-independent and has its own virtual machine that is capable of converting the code into bytecodes which can run on all java supported platforms

• Java is an object-oriented programming language that is based on objects which are capable to imitate real-world scenarios

• It supports the four pillars of an object-oriented programming language. I.e., Abstraction, Encapsulation, Inheritance, and Polymorphism

• It is more secure than other contemporary programming languages

• Java does not support pointers and multiple inheritances as they cause ambiguity and lead the programs to crash 

• Java supports threads and therefore can execute multiple tasks simultaneously occupying much less memory

• It uses a Just In Time compiler that uses the best of a compiler and an interpreter

These Java benefits are also some of the top reasons why you should prefer taking Java courses online free.

What is Java Programming Used For? 

Now that we know what Java Programming is, we must also understand what it is used for. Java is used by developers across industries to consistently upgrade their models and remain competitive with modern technology standards.

Some of the many areas where Java is used as the primary programming language are:

• Development of server-side applications 

• Developing HTML forms, online forums, e-stores, polls, etc.

• Creating customized applications by combining multiple basic applications 

• Running software on virtually any java supported platform

Great Learning's Java full course will make you adapt to working on all such applications and softwares.

Coding powerful applications for:

• Mobile devices

• Remote processes

• Wireless modules

• Microcontrollers

• Sensors

• Gateways

• Consumer Products, and more

Variables in Java Programming

Variable is the name of the memory area where the information is put away. You would need to remember a couple of things while working with factors in Java. 

• A variable name should start with a letter, $, or an underscore symbol(_) 

• The principal letter for the sake of the variable can be trailed by any combination of digits and letters 

• The variable name ought not to be the same as keywords on the grounds that the watchwords are held for unique purposes.

• Variable names are case sensitive

The three types of variables in Java Programming are: 

• Local Variables

• Instance Variables

• Static Variables 

Data Types in Java Programming

There are various kinds of data that one deals with within business applications. To handle them, we need various sorts of data types and containers as storage. In Java, there are 8 data types: 

byte – size is 1 byte and it holds 0 

int – size is 4 bytes and it holds 0 

short – size is 2 bytes and it holds 0 

long – size is 8 bytes and it holds 0L 

roast – size is 2 bytes and it holds '\u0000' 

boolean – size is 1 cycle and it holds false

skim – size is 4 bytes and it holds 0.0f 

twofold – size is 8 bytes and it holds 0.0d 

There are likewise some non-primitive data types like arrays, classes such as String, etc.

Operators in Java Programming

The various kinds of Operators in Java: 

• Unary Operators

• Arithmetic Operators

• Shift Operators

• Relational Operators 

• Bitwise Operators

• Logical Operators 

• Assignment Operators 

• Ternary Operators

The roles and responsibilities of a Java Developer

A Java developer is expected to perform a set of tasks and to take up specific responsibilities which are as follows:

• Create Program Architecture - The program design is the critical factor that gives a general vision of what requirements to achieve from a task. Java developers are needed to introduce this design, given their capability with Java. 

• Requirement Gathering - Before taking a shot at a project, a Java developer must assemble requirements from those associated with the planning process. This incorporates working intimately with the stakeholders and project managers alongside other java developers. This stage will likewise incorporate prioritizing tasks, deciding the extent of work, and settling the course of action. 

• Development - This is where the Java developers will actualize their core abilities, i.e., developing the code, testing, and correcting the code. 

• Testing - As the development gets completed, Java Developers test and debugs them. The objective is to guarantee that all the features fill in as they were planned. 

• Deployment- The deployment stage includes moving the code to a live environment. The code should be completely functional before the developers begin deploying it. The changes that must be done will have to be made in the testing stage. Changes after deployment would require reverting and redeployment.
