Quick Setup (< 1 hour)

You can use IntelliJ IDEA to write, test, and maintain code primarily for Java and Kotlin applications. It provides built-in code completion, deep code analysis, refactoring tools, and integrated debugging. You can run automated tests, inspect Spring framework setups, and explore database connections directly within your workspace. The environment also supports connecting different AI coding agents to write or review code, run terminal commands, and inspect application performance. It handles large codebases efficiently while providing version control integrations like Git for commits and branching.
