IntelliJ IDEA's Inline Method Refactoring

You can trigger it by placing your cursor on the method you want to inline and pressing the Refactor This shortcut (Ctrl+Alt+Shift+T on Windows/Linux, or Ctrl+T on macOS) and selecting 'Inline'. Alternatively, you can right-click the method and choose Refactor > Inline from the context menu.

IntelliJ IDEA automatically analyzes the method's parameters and replaces them with the actual local variables or values passed in by the calling method. This ensures the integrated code maintains the exact logic and behavior of the original, self-contained function.

Yes, IntelliJ IDEA will prompt you to choose whether you want to inline the method in just the current instance or delete the method entirely and replace all of its calls across the project. It safely updates every reference to maintain your code's structural integrity.

Inlining a method alters the code structure by pulling logic directly into the calling method, but IntelliJ integrates smoothly with version control systems like Git. The refactor itself is a safe semantic operation that simply stages the changes locally without corrupting your commit history.
