7 Tips to Be a Good Java Developer

Knowing the programming language is not sufficient to become a great Java developer. Being an expert in Java programming and coding is necessary for creating a quality application.

It’s important to remember that you’re not alone in the race because Java is one of the most popular programming languages. An estimate places the number of enthusiastic Java developers at around 9 million. Java developers are well-versed in technology and eager to learn about new Java features like Java 8, JDK 10, and JVM internals. 

There must be some distinctions in your abilities, effectiveness, and outlook for a Java app development firm to choose you over the rest and hire you to help them create a solid Java program. 

Here are some fascinating statistics that explain why there is such a high demand for Java programmers. 

Oracle, a successful American multinational computer technology business, currently oversees Java. This indicates that Java has a lot of room to expand both as a platform and in terms of its primary APIs. Platform Standard Edition 8 is Java’s most recent significant update.  After C, Java is the most popular programming language. According to software developers, this language is the finest option for programming languages. The Java API is also used by Google’s Android operating system.

It should come as no surprise that 95% of businesses utilize Java as their primary programming language since it is an open-source programming language used for both software and web development. That surpasses the combined capabilities of C and other languages. These details show how crucial Java is for businesses of all sizes. If you want to be hired as a Java developer then you also need to have exceptional Java development abilities.

Practical tips for becoming a Great Java Developer

Be a Good Java Developer

For a wide variety of devices, including smartphones, computers, laptops, gaming consoles, car navigation systems, lottery terminals, Blu-ray players, and more, Java is used to create a wide range of applications and platforms.

Here is a list of Java hints to provide you with an idea of how you might enhance your Java programming abilities to create apps for these gadgets.

1. Study Java 8

Many Java developers in the market, even those with seven to eight years of experience, are still unsure of how to write code that takes advantage of Java 8 features like Lambda Expressions, the Java Stream API, which is used to perform bulk data operations on collections, and various Default Methods.

If you develop a solid grasp of Java 8 features, you can surpass many Java developers who are currently working in the field but have little to no experience with Java 8.

With the introduction of the iterable interface, developers may concentrate on business logic while writing code. It is possible to keep business logic separate and in a distinct location so that it can be reused later by using a consumer object as a parameter.

Using Lambda Expressions and Functional Interfaces: In Java 8, a brand-new idea called functional interfaces was introduced. @FunctionalInterface annotation is a tool to prevent the unintentional insertion of abstract methods in functional interfaces. An interface with precisely one abstract method becomes a functional interface.

2. Stream API for Java

In Java 8, a new java.util.stream has been created to enable similar filters, map, and reduce operations on the collection. Developers will be able to control both sequential and parallel execution thanks to the new Stream API.

Learn Java APIs and Libraries to the Profession

Java has the second-largest StackOverflow community, making it one of the most developed programming languages in existence. The community is essential to the development of the Java ecosystem.

A significant component of this ecosystem is the Java APIs and Libraries. One of the essential qualities of an excellent Java developer is their familiarity with important APIs and libraries, such as the Java Development Kit and Third-party Libraries.

The Java SE documentation includes thorough, developer-focused explanations and references to the Java API, workarounds, and actual functioning code samples.

Developers of Java applications are optional to be experts in all APIs and library components. The only requirement is that the developer, whether a Freelance Java Developer or one employed by a Java Development Company, be knowledgeable about essential APIs and Libraries.

3. Study the Spring Framework (Spring Boot)

Every Java Application Developer needs to be familiar with this Java platform.

It allows programmers to create apps using “plain old Java objects” (POJOs), and it is also helpful for the Java SE programming model.

For the development of web applications, microservices, and REST APIs nowadays, the majority of Java Development Companies employ the Spring framework, including Spring Boot, Spring MVC, and Spring Cloud.

An excellent Java developer will be familiar with all the benefits of the Spring platform, such as making a Java method run in a database transaction, turning a local Java method into a remote procedure, and turning a local Java method into a management activity.

4. Put JVM Internals First

You must have some working knowledge of Java Virtual Machine (JVM), a critical component of JRE, even if you are starting in Java Application Development (Java Runtime Environment).

Knowing JVM indicates you are more knowledgeable about Java. 

You will be able to write programs more effectively when you know JVM. Learn how the Java Virtual Machine (JVM) operates, including its system threads, how Java bytecode is executed, and the sequence of execution if you want to become a great Java developer. Restrictions on the JVM stack and typical errors committed by Java developers are some additional crucial elements you should be aware of if you want to improve your Java skills. 

Acquire More Practical Design Pattern Knowledge You must be aware of the significance of Design Patterns in Software Development if you have expertise in developing object-oriented software. 

The relationship between classes and objects is shown through design patterns. Methodically naming objects and classes can solve the recurring issue in object-oriented systems.

Every smart Java developer is aware of design patterns and uses them in their code to give the programmer flexibility and adaptability.

5. Read up about JVM Languages

Knowing programming languages that are not Java is beneficial for Java application development just as learning new languages is beneficial for your personal and professional life.

Programming in Kotlin, a statically typed language that utilizes the LLVM compiler infrastructure and runs on the Java virtual machine, has several output options, including compilation to JavaScript source code. 

Mastering JVM languages like Scala, Groovy, and Kotlin is essential if Java fans want to become polyglot developers.

Gaining a deeper understanding of the advantages and disadvantages of different programming languages will help you create better code. The development of Android will also benefit from it.

Concluding Remarks

Explore the latest features of Java 8 while also learning new programming languages to improve your expertise if you want to become an expert in Java and value learning new Java programming and coding skills.

The ideal course of action is to concentrate on Java 8’s capabilities, as you require Java 8’s functionality for any application development process.
