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?

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

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.
