Best 3 Online Java Compilers

java-dev

A Java compiler is a program developers use to compile Java applications. It converts your high-level Java code (.java) into platform-independent, low-level bytecode (.class). The conversion is an essential step in the Java application life cycle since the Java Virtual Machine (JVM) can only understand bytecode.

However, new developers often get confused between Java compilers and Java IDEs. IDE is a tool that consists of various features to help the development process. For example, Eclipse, IntelliJ IDEA, and NetBeans are some of the most used Java

Due to this increasing popularity, various java plugins, IDEs and compilers were introduced to make developer’s life easier. To give you a better understanding of the best online java compilers available, as well as to facilitate your choice of compiler, we have listed the top 10 online java compilers available in the market.

Java is one of the most used programming languages in the world. It allows developers to quickly build robust, resilient, scalable, and secure apps. According to Statista, Java was used by more than 35% of developers worldwide in 2021.

Benefits of Using Compilers

Compilers convert a high-level language into low-level code, allowing the processor to understand the code. Although this is the primary task of a compiler, it is capable of much more than that.

Here are some of the most significant benefits of using a compiler:

  • Compilers generate executable files which are capable of running without the source code, improving the security and privacy of your program.
  • Compilers are faster than interpreters.
  • No additional applications are needed to execute the executables since compilers generate them based on the OS.
  • Generates machine code specifically for available hardware. So, your application can optimally run on any hardware specification.
