How to Choose the Best Online Java Compiler and Runner

We bet you’ve ever been in a situation like this before. You’re coding, doing your thing and everything is going great! Then the devil reincarnates himself in the computer in front of you, and the C++ compiler you were using just crashes. Aaargh! You just want to throw it from the tallest building and watch it smash into a thousand pieces!… Well, um, we don’t advocate for that.

What if there was a saner way of getting your work done without incurring the cost of a new computer? Well, there is! Because we’re here to help. Today, we’ll be discussing the best online Java compilers and runners you can find. But before we get into the juicy stuff, for the newbies reading this (we love you guys), let’s give you a crash course on what a Java compiler is and whether it’s handy in the Java functional programming.

What Is a Compiler

A compiler, in general, is a unique program that reads and processes information written in a given programming language and then converts the data into machine language; of which a machine can then utilize to execute a given function. There are quite a number of languages that a programmer can use to write codes and statements. Some worth mentioning are FORTRAN, COBOL, C, C++ and of course; the one, the only, the heavyweight champion…Java!

What Are the Pros and Cons of Using a Java Compiler?

  1. Programs created by compilers are efficient and further self-contained. One of the biggest advantages of using a compiler to create a program is that the program ends up being self-contained. What do we mean by this? Well, programs have already been compiled in machine language, thus they are ready to be read and executed by machines. You don’t have to purchase a second application. or some kind of package for execution. For example, say the program is compiled for Windows 10 on a 64x bit processor, all you require is Microsoft’s Windows operating system and you’re good to go!
  2. There is great hardware optimization. Despite the fact that focusing on one hardware package has its disadvantages, compiling a program specifically for the package in question can further increase the program’s performance. That’s because users of a program can be able to send specific and detailed options to the compiler regarding the specifications of the hardware it will be executed on. This then allows the compiler to generate a machine code that is extremely efficient under the hardware in question; as opposed to a more generic setup. One can truly optimize the performance of a program to suit their needs.

  1. Compilers cause programs to be hardware specific. The function of a compiler is to translate given code into a specified machine language. Because of this, the programs created are designed for specific operating systems such as Microsoft’s Windows, OS X, Linux; just to mention a few. That means for a programmer who is trying to market his product to a large audience, the developer must create different versions of the given code to be compatible with different systems. The developer thus has to spend days or even months doing that! And this ultimately delays the whole project.
  2. The compile time for large projects is exhausting. When it comes to creating simple programs, a compiler can be quick and awesome. You can get the program up and running in no time. The same cannot be said however for large projects. They can take quite a large amount of time to be compiled. This is especially so during the development stage. Oh, how much time programmers can spend just being idle!

So now that you are aware of the pros and cons of using a compiler during programming, you can plan yourself accordingly. If you are a pro-java compiler fan, here are 5 online java compiler websites that can be really helpful to you!
