@applejack @hj @lanodan You can use Java without an IDE. I normally do most of my Java assignments using Vim and the Java compiler.
javac <insert java filename here>.java
@applejack @hj @lanodan It creates a class file of the Java file. All the imported files it uses are also compiled to class files. To compile to a JAR (Java executable) file you enter:
jar -cf <insert output filename here>.jar <insert class file here>.class
@xianc78 @hj @lanodan Never seen it. I even remember trying to look for it once. I've done some java programming and I have no idea how I'd set that up
