What is Java?
Any operating system or device that has the Java Virtual Machine (JVM) installed can run and then utilize the programming. This allows the language to run on multiple platforms. It is also a static language so variables do not need to be defined to be used. While many have criticized this as a dying language, year after year, it continues to remain at the top of many rankings as one of the most popular programming languages used. Java is predicted to continue to dominate in 2022.
Knowing that these are two different types of languages with varying uses, it is important to look at the advantages and disadvantages of each programming language.
What are the advantages of Java?
- It is a secure language.
Since code is grouped, this increases security levels. Explicit pointers are also not used and a security manager is in place for each application with rules for access. Government agencies and investment banking companies lean to this language for this important feature.
- The language is object-oriented.
Code can be flexible and reused. Many use the slogan “Write once, run anywhere” when it comes to Java.
- Established libraries and frameworks can cut down on development time.
Pre-written code makes life easier for the programmer.
- Bugs are found during compiling.
This is an advantage because errors can be found, and fixed,
before run time.
- The language is portable and platform-independent.
Code is designed to be written once and then be used on multiple operating systems and platforms.
- It is a high-level programming language.
Since it can be easily read and understood by humans, Java is considered high-level.
- It automatically manages memory.
A garbage collector — the memory management system — is used to manage memory automatically. The JVM runs the garbage collector when memory is getting low.
- It can connect to databases.
With Java Database Connectivity (JDBC), Java can connect to
databases and provide queries.
What are the disadvantages of Java?
- Java can be relatively slow to start.
Many consider this language slow to start because the JVM has to run first so that Java can be processed on any operating system. All code written in this language has to be compiled and abstracted before being able to run on an operating system. This takes time at the start.
- It requires a lot of memory space.
The JVM takes memory when it needs to execute logic but still keeps the memory on reserve, even after processing.
- It does not have a backup.
Backing up data is not a focus and it operates by using storage space.
- Codes are long and complex.
While Java works to be more manageable and reusable, this results in codes being longer and more complex and require longer explanations.
- JS is relatively fast to run.
- Libraries and frameworks can cut down on development time.
Well-established libraries of code and frameworks are available that lessen the time needed for programmers to create their web designs. Animations, forms, background images, and more can easily be added with established code.
- It can enhance the user experience by making web applications interactive.
- It runs on the client-side web browser without needing to use the server-side.
This is beneficial as it allows for less demand to be put on servers.
- Bugs are found at run time.
Debugging does not happen prior to execution and largely depends on the platform over which JS is being executed.
- It is not very secure.
decreases its level of security.
This can take time and cause frustrations for the programmer.

Career/Job titles for Java and Salary
Careers that utilize Java are in high-demand and compensation reflects this. According to indeed.com, the following average salaries were found for Java-related career fields. Octoparse ranked Java eighth on its list of “15 Highest Paying Programming Languages.”

Java is so popular because it can be written once and used on a variety of operating systems — mobile or desktop. Developers are generally responsible for not only designing Java applications but also implementing and maintaining the applications. They should be able to write efficient and workable code and also test and debug the code. They work with project managers, design leads, and software engineers to plan and deliver projects for their companies. This is one skill for back-end developers to learn in order to write web applications. Software architects and developers utilize Java as a skill to make them more marketable since it is one of the top programming languages in the world.

As both languages remain two of the most popular programming languages in 2022, it is clear that learning either language (or both) can only be beneficial. Each language has its distinct strengths and for each, it seems that the advantages outweigh any disadvantages.
