Java is an important language that is used in many different areas of programming. A Java compiler is a software tool that translates Java code into a higher-level language. As the popularity of Java continues to grow, so does the need for good Java compilers.
In this article, we will introduce you to the top 10 Java online compilers in 2022. After reading this article, you will be able to make an informed decision about which online compiler is best for you.
What is Compilation?
The compilation is the process of taking a program written in one programming language and converting that into a different, machine-executable code. Wikipedia defines it as: “compile / compiler/kümi’lepayiraje – to convert (source) code written in human languages such as English or French…for example… translating from Java to C++.”
How to choose the best Java online compiler?
As with any other programming language that is evolving rapidly over time, the need for an excellent compilation tool continues to grow. However, it’s not just about the quality of a compiler; in this article, we will also give some insight into features and functionality so you can make sure you are selecting exactly what your business needs from their compiler.
So let’s get started! After reviewing each methodologist presented below which offer Java online compilers, be sure to read our article on what you should consider when choosing a compiler and we will also provide some important considerations you should always make note of before making your final decision.
Each compiler you choose will have a different set of strengths and weaknesses so it’s important that you understand the following two points well:
Compiler 1 Compiles
- Is more proficient in turning your Java code into bytecode
- Can still use existing libraries from other languages such as C & P, can convert legacy enums to interfaces. When using these types, we strongly recommend searching for compatibility with their version of libGDX then adding some language features if needed via annotation, (example: @Ignore unused)
Compiler 2 Does Make Use of Online Database Maintenance
- Can generate a new build independent from any version control system
- Supports compatibility with 3rd party libraries such as libGDX.
When using these types please search within their documentation and use the feature request link above to report bugs against your IDE if available. If not issue us a Feature Request instead so that we may present those results here.

Conclusion
When selecting a Java online compiler, it is important to understand its strengths and weaknesses. For example, Codiva’s compilers are more proficient in turning your Java code into bytecode and can still use existing libraries from other languages such as C & P, but they don’t support compatibility with libGDX.
On the other hand, JDoodle’s compilers generate new builds independent from any version control system and also supports compatibility with 3rd party libraries such as libGDX. JDoodle tends to have slightly faster compilation times than does Codiva, but Google Code-in also boasts decent build speed and compatibility with many 3rd party Java libraries that are not supported by codiva (such as RCP/JSR 349).
