But the question arises that what is a java developer and what are its responsibilities? Java developer collaborates with the software engineers and developers to combine java into business software. Java developers must manage the design, implementation, testing of java applications throughout the development cycle of the software or website. Java developer helps to transform the requirements into stipulations and developer the technical designs for application development with the help of java programming language. They are also responsible for identifying production and non-production application issues along with being part of software analysis activities. Now you must be wondering that how to get a job as a java developer in this competitive age of technology?

Roadmap For Becoming A Java Developer in 7 Weeks

Learning new technology is very tough if you don’t know the process to learn it. Learning java is not about writing a “hello world” program, but is knowing java well enough to get you a job as a java developer. Here we will provide you with a perfect roadmap that helps you to manage your learnings and revisions from basics to advance and become a professional java developer. So, let's begin to take a look at how to become a java developer in 7 weeks.

Java Developer Roadmap

Level 1: Beginners Topics (2 weeks)

As a beginner in the technological world, you are completely unknown to programming and what theories and concepts you should learn to start programming. So for the first week of your java developer roadmap, we will learn basic java programming. The important topic that you should cover as fundamentals of java are given below:

  • Syntax Of Java: Every language has its syntax to work with. If you make any mistake in the syntax of any programming language while working with it, it will show an error and you will get stuck. So first and foremost task is to learn the syntax of java as a programming language.
  • Data Types: As the basics of programming language, it is important to get familiar with data types that hold different types of variables to store data in the memory of the system while programming.
  • Data Structure: Data Structure is data management and organization formate to store the data while programming in java. Java supports many types of data structures like string, integer, float, boolean, etc
  • Basic Logical Operations: Logical operations are the operations that manipulate the Boolean values to check whether the conditions are true or false. Generally, logical operations are used while working with conditional statements or loops. 
  • Conditional Statements: Many times while programming, we need to check whether the given condition is true or not for executing some specific statements. Conditional statements help for such tasks in coding. if, if..Else, if..else if..else are some of the conditional statements in java.
  • Loops: Loops are similar to conditional statements that are executed when the condition becomes true. While loop, for loop, are some of the loops in java

Level 2: Intermediate Topics/OOP Concepts (2 weeks)

Java is an object-oriented language just like C++. The students who have no idea of OOP concepts and direct switching to object-oriented language from procedural language, will not be familiar with certain procedures and concepts like creating objects, class-object hierarchy, etc and there are chances that they might face difficulty initially. But with proper practice, you will get familiar with these concepts and the advantages of OOPs. Some of the OOP concepts which are recommended to learn on the path of becoming a java developer are:

  • Class: A class is like a blueprint to define a variable and methods for objects of a certain kind. Therefore, we can say that class is one of the defining methods of OOP.
  • Object: Object is an instance of a class in java programming. We can say that object contains some specific methods and properties to make the data useful.
  • Constructor: Constructors are special members of the class. They are executed whenever the new object is created. The constructor has the same name as the class name. it also does not have any return types, not even void.
  • Encapsulation: In OOP encapsulation means combining the attribute and behavior of the class along with restricting the access of the inner working of the class.
  • Abstraction: Data abstraction is the process of hiding the information from the outer world and only provide the data needed to hide the rest of the details.
  • Inheritance: Basically, inheritance helps us to define a class based on another class. Thus this provides the facilities to create and maintain the application.
  • Polymorphism: The basic meaning of the word polymorphism is having many forms. Generally, polymorphism occurs when there is a hierarchy of class-related by inheritance.

Apart from this, there are many other OOP concepts like this pointer, friend function, exception handling, lambda function, etc. It will take 2 weeks to learn and practice all the above OOP concepts for preparing yourself for future java projects and applications.

Level 3: Coding Practice (3 weeks)

As java is the most demanding programming language in the emerging technological world, it is not enough to mention “I know java” in your resume to get a java developer job. For this, you have to build beginners projects and work on some amazing real-world projects to convince recruiters to hire you because it is easier to demonstrate that one knows java if they have a few java projects on their resume. Below we have mentioned some of the java projects you can refer to shine your resume.

  • Bank Management Software
  • Electricity Billing System
  • Chat Application
  • Digital Clock
  • Student Management System
  • Food Ordering System

Apart from this, you can go through other amazing java projects in detail and practice them to land up as a java developer in your dream company.

How Much Java Is Enough For Getting A Job?

The answer to this question depends on how effective you have worked to pursue your career as a java developer. If you have understood the basic and advanced java concepts and practiced applying them in the real world, you are good enough to get a job as a java developer. But if you have just understood the concepts and never learned to apply them by practicing coding and projects, then it is recommended to do that. To become a java developer as a fresher it is advisable to work with some intermediate and advanced topics along with some java frameworks which most popularly used in the tech industries. Spring and Hibernate are some of such java frameworks which are mostly used by industries and recommended to learn and apply after understanding intermediate and advance topics of java.

Conclusion

It is not just the knowledge of the programing language which can take you to the path of being a developer. To become a java developer, one has to follow a perfect roadmap with all necessary practical demonstrations which can lead him to get his dream job as a developer. Remember, if you follow the pathway and practice enough to show your skills to the recruiters, the doors of IT industries will be open for you a java developer.
