What makes a good Java IDE?
An IDE, or Integrated Development Environment, bundles all the tools you need to write, debug, and test your code. An IDE allows developers to work in a single environment and improve their programming workflow. Each IDE has different resources, but they all include a text editor, build tools, and a debugger.
When deciding on a Java IDE, it’s important to first determine what you need out of it to ensure that it has the essential tools for your needs. No matter your experience level, there's an ideal Java IDE for you.
Essential Java IDE tools
- Debugging: While debuggers vary among different IDEs, it’s important to have a tool to highlight potential errors and help you step through your code.
- Syntax highlighting: Built-in highlighting is crucial for readability and efficiency. This tool can help you find errors in your code and allows you to sift through your code at a quicker speed.
- Build automation: A good IDE will allow you to write and run your Java code in the same window, increasing the productivity and efficiency of your program.
- Code completion: This tool identifies and inserts code components to save you time and lower the risk of typos and bugs.
- Graphical User Interface (GUI): An effective GUI enables an intuitive programming interface.
