9 Pros and Cons of Being a Java Developer

Java’s popularity of learning makes people pursue this career path. But many of them do not know the pros and cons of this job. This fact is very worrying because someone will choose the wrong career path.

To help you understand its duties, we will dive into the benefits and problems of a Java developer. Keep scrolling to discover what they are!

What does a Java Developer do?

Java developers use the Java language to create and develop software and applications. They can also do web programming with Java.

They join in the product life cycle, from concept, and design to testing. Then, there is the maintenance task. They must identify and analyze problems. This process is for data analysis and quality assurance.

So you already know what a Java developer does. Let’s explore the pros and cons of this job in the following sections of the article!

Coding with Java

Let’s dive into the pros of Java developers to get a broader view of this job! We have surveyed many developers and have compiled six benefits:

1. Java is Simple

Everyone thinks that Java is friendly to beginners. Although simple, Java is a diverse and high-level language. It allows users to focus on programming rather than mechanical details.

Its advanced management tools take care of memory allocation. These tools help Java developers work faster.

Another reason is that it has similar sentences to English. So you can remember them even if you have never learned to program.

2. It Features Object-Oriented Programming

Object-oriented programming is a definite coding concept. It refers to data type, structure, and functions. This feature allows them to create relationships with other objects.

This benefit allows Java developers to reuse objects in other programs. Besides, these objects can hide sensitive data and limit errors. As a result, system maintenance becomes much simpler and more efficient.

3. Java is a High-Level Language

While Python and SQL have grown over the past few years, many IT companies have used Java for decades. That is because of its availability and flexibility.

You can find Java in most operating systems from the web to mobile to desktop. It is popular in business applications and the Android mobile operating system.

Besides, it updates to keep up with trends and can support many languages on its platform.

4. It is a Secure Programming Language

Without explicit pointers, Java helps developers avoid safety and security dangers. Because they hold the memory addresses of other values, they can allow unwanted access to the system.

This language also has a security manager for every application to use. This feature specifies access policies for every layer.

5. Java Offers Various APIs for Application Development

The large APIs collection allows developers to use them for most applications. They have access to many APIs for multithreading.

Another benefit of this language is that it can be compatible with many languages. By learning Java, you can apply it to almost any other programming language in no time.

6. It Supports Multithreading

One of the pros of Java is its support for multithreading. It allows threads to run in a program. With this feature, you will create and manage them with ease.

Java also provides a rich set of tools and APIs to control their behavior. With these tools, a program can use modern processors and allow you to manage tasks in parallel. This feature is helpful for intensive tasks.

Besides, with Java, developers can interact with the application and perform background tasks. You will see this benefit clearer when performing tough tasks.

Overtime work is regularly

So is there any con to being a Java developer? The answer is YES! Here are some problems with this programming language that keep many people from choosing this job.

7. Verbose and Complex Code

While this problem shouldn’t be too hard for developers, it should still be on this cons list. As a high-level language like human language, it contains long and complex sentences.

This feature makes it difficult in some cases. Developers have to find the optimal way to solve this problem.

But developers can more easily manage them than other languages. So if you know how to handle it, this will not be a problem.

8. Poor Performance

Many Java developers say it has poor performance. Every Java machine-level code leads to low performance. Compared to native languages like C++ or C, Java consumes a lot of memory.

Besides, garbage collection is available. Although helpful, this function can cause serious performance problems. That is because it uses many CPU resources.

This con is why some people turn to other career paths instead of becoming Java developers.

9. It Lacks a Native Look and Feels When Used for a Desktop

Java is a bit weak in optimizing the interface and user experience on the desktop.

In other words, its applications can often appear out of place on the user’s operating system. It also does not match the look and feel of other native ones on the same machine.

To solve it, Java developers can use third-party libraries such as JavaFX or SWT. They provide a more native look and feel to operating systems.

JavaFX, for example, provides a more modern interface on desktop platforms. Meanwhile, SWT is for Windows.


You now know the pros and cons of being a Java developer. This job is hot because Java is popular and easy to learn.

Many people do not want to go this route as it can have low performance. You must understand these notes and consider whether to pursue this career.
