What was the best part about using Eclipse?
What I like most about Eclipse is that Eclipse does everything. Every language, every tool, all the plugins, marketplace, sql, test tools, automation, version control, searching, editing, html, javascript, java, c, c++, scala, groovy, enterprise java, spring, etc. Using Eclipse, you can easily combine language support and other features into any of the company's default packages, and the Eclipse Marketplace allows for virtually unlimited customization and extension.
What would you change about your experience with Eclipse?
I think, Eclipse has just about anything you could want from an IDE, though sometimes a bit more complicated than one might like. It takes lots of time to load and a lot of memory though it is not the fastest, and the interface could be improved. Also, you can sometimes get some weird errors while you are programming like the program says that "doesn't find any binary files" when the binary files are ok.
Overall Feedback
If you can't afford an expensive and advanced IDE, Eclipse is a great open source alternative to run on multiple platforms. It is free and it supports all kinds of programming languages. It has a huge library of plugins to help with whatever project type you're working on. I have used Eclipse for programming at home in C, Java, Python, HTML + Javascript, and also at work mainly for Python development. Eclipse compiles all the code in real time, pointing out any bugs you may have to solve. The good debugging nature of Eclipse made me to use this as my primary tool to run java and other applications. It's been around for years and with every upgrade it is getting better.
