Do you know a good, free Java compiler?

Question

I'm learning Java and was looking for a basic compiler, but had trouble finding one that worked well. If you know of any C++ compilers, I wanted to learn that too, but they were much harder for me to find.

Answer 1

Have a look at the free Watcom C/C++ compiler:

For all things Java see:

Answer 2

BlueJ is a brilliant learning tool, why? Because it's created for students (well, beginners) learning Java. It's known quite a lot around Europe. The beauty of it? It provides everything in a visual way. Any class you make it displays in a UML like diagram, it shows how everything connects with the variables etc. and you can right click on any class to make an instance of it, and call any method which is really nice when you want to set your head around it.



Once you have the nack of that, you can move onto the big daddies like NetBeans.



Ironically it was made by some guys, and one of them lectures at my University which is the next town along from my home town (which is not the reason I recommended it). But it's a beautiful learning tool! Check it out: www.bluej.org



If you're really into it, the book is a good read as well (I had to buy it as it was a book for one of my modules), but you can get along with out it. If you like, download the "projects.zip" which is seperated into chapters.

Answer 3

The java compiler comes with the java software development kit found at java.sun.com



It's command line. A simple-to-use development environment that you can use with Java is JCreator (and lets you press a button to compile your code, instead of doing all that work of adding stuff to your PATH and then typing into a command line javac sourcefile.java and then java sourcefile.class to compile and run it.



The GNU Compiler Collection GCC, also known as Gnu C Compiler is one of the best-known free C compilers, it is also "professional grade", and it also compiles C++ code. The unofficial windows port is DJGPP

Answer 4

download a copy of textpad.



It is a simple text editor that will color code different types of code ie: strings vs integers., it will compile and run your java code all from one program. Works great
