![]() ![]() Here are two videos that walk through how to set up an IDE and run Java code. You should download and install Java to your computer before using an IDE. We recommend IntelliJ IDEA, which you can download for macOS, Windows, or Linux. The biggest benefit to using an IDE is that it allows you to code and run Java programs on your own computer. IDEs also provide hints while coding to prevent errors before compilation. When a program does not run correctly, IDEs provide debugging tools that allow programmers to examine different variables and inspect their code in a deliberate way. No programmer avoids writing bugs and programs with errors. This compilation process is necessary for every program, so why not have the IDE do it for us? IDEs provide automated build processes for languages, so the act of compiling and executing code is abstracted away, like in Codecademy lessons. Once compiled, the program can be run from the terminal. java file must be transformed into an executable. The source code of a program is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source code. Before programs run, the source code of a. This saves keystrokes so the programmer can focus on logic in their code. In an IDE, we might see System as an autocomplete option after only typing Sy. We’ve seen statements with () quite a bit so far. When the IDE knows your programming language, it can anticipate what you’re going to type next! Syntax highlighting makes code easier to read by visually clarifying different elements of language syntax. ![]()
