Looking to get Job as a Java Developer, then you are at the right place. Here, I will discuss the skills required to get Job as a Java Developer.
First and foremost let me discuss What Java Developer Role is all about. Java Developer is responsible to design, develop, and solve a particular problem using Java Programming Language. If you want to become Java Developer, here, we will discuss the set of skills required to get Job as a Java Develoeper.
Note: We at Codebun are providing all these services to help students or working professionals who want to learn real-time application development using Java.
As a fresher, the skills required to get a job as a Java Developer is as follows:
Core Java
There is a great saying “you can’t build a great building on a weak foundation” by Gordan.B.Hinckley. It is absolutely right. If you planning to learn Java, the core of the language should be as strong as possible. You should have a basic understanding of what Java is all about. The core concept should be crystal clear(when I say crystal clear, I mean it). Check this link for core Java https://codedec.com/course/java-tutorial/.
To learn Core Java, the following are the topics you should master
- Basics of Core Java(Introduction to Java, its History, Features)
- In-depth knowledge of JDK, JVM & JRE.
- Well-versed with OOPs concept. (this concept should be crystal clear with Examples)
- How Memory Management works in Java.
- Package Structure in Java
- Data types, Wrapper classes, variables, constants, methods, modifiers in Java.
- What are Constructor in Java and its type?
- keywords such as static, final, super, this and etc.
- Inner Classes in Java.
- File Input and Output Stream
- Collection Framework and its Hierarchy.
- Serialization, Exception Handling, String concept.
- Design Pattern in Java.
- Multithreading Concept
Now, once you are done with core concepts, don’t forget to learn Java 8 Features. Have a good understanding of the following Java 8 features:
- Functional Interface.
- Lambda Expression
- Method References.
- Stream API
- Optional class
- ForEach() method
- Date and Time API
Practice Core Concept
It is not enough that once you understand the above concept, then you are good to go. Now, you need to practice a lot to get a good grip on the concepts. Start coding as much as possible.
For Example, once you are done with the String topic, try to solve as many as problems of String without using the inbuilt function. Do this for every concept. Solve real-time problems using Java Programming Language. Look here for examples https://codedec.com/course/java-tutorial/.
Learn SQL | JDBC
When you will be learning Java, you will get one topic JDBC, i.e Java Database Connectivity. Here, you will need to interact with the Database. So, you should be able to interact with it using SQL Language. SQL is one of the popular languages to access data from the relational database.
Learn all the concepts of SQL. Learn relational Database MYSQL, Oracle, and etc. Now, with the help of JDBC learn how to perform CRUD operations. Let us see the concept that you should know:
- All CRUD Operation.
- Keys in SQL, CONSTRAINT in SQL
- Join Concept
- Normalization
- SubQuery
Now, as you are done with the core concept, then it’s time to move on to J2EE(Java 2 Platform, Enterprise Edition)
J2EE (Advanced Java)
Now, it’s time to learn the advanced concept of Java. Here, If you want to go for web development you should know Servlet technologies, JSPs, and etc. Advanced Java concept would help you design applications that would run on the server. With the help of this, you can create an Enterprise Level application. If you want to learn Servlet and JSP check this link https://codedec.com/course/servlet-tutorial/ & https://codedec.com/course/jsp-tutorial-for-beginners-with-examples/
Now, once you understand Servlet and JSPs, try to create a simple web application by combining it with frontend technologies such as HTML, CSS, Bootstrap, and JS. The most popular application you can develop is Electricity Billing System, Bank Management System, Student Management System, and etc. You can check the ideas from here Java Project Ideas 2022
Learn Frameworks
There are lots of framework available which makes thing easy for us. Once you create a simple web application using advanced Java, then you will come to know that at the data access layer you have to write too many queries. Here, we have ORM Framework that would help you out at the data access layer which is Hibernate which again is the most popular framework we have and many companies are using it. Check this link to know about Hibernate https://codedec.com/course/hibernate-tutorial/
Then, we have another popular framework called Spring Framework that has lots of modules such as Spring MVC, Spring Boot, Spring Cloud that makes it super easy for us because of its dependency Injection concept. Learn both the framework inside-out. Check this link to know about Spring Framework https://codedec.com/course/spring-mvc-and-spring-boot-tutorial/.Check this link to know about Spring Boot https://codedec.com/course/spring-boot/
At last, use the Spring Framework module and Hibernate Framework and create projects using both which will surely get you a good understanding of the overall framework. Check this link for Spring & Hibernate Projects https://codebun.com/category/project-in-spring/
Tools
As we know, to work as a Java Developer, we require some tools. So, have a firm understanding of IDEs such as:
- Eclipse IDE
- Spring STS
- IntelliJ IDEA
At last, learn Maven/Gradle for Project Management because it is one of the powerful management tools that is based on POM(Project Object Model). It will help you to download the dependency and libraries needed for your project.
Thus, follow each step, work hard, be consistent, and nothing can stop you from getting a job as a Java Developer.
Note: If you need the source code you can contact me. We will provide complete source code and all the required things like Database. We have created a STEP by STEP configuration tutorial to help you in the configuration process.
