Keyboard Shortcuts for Efficient Coding in Java with IntelliJ IDEA

Editing with Speed

IntelliJ IDEA offers a comprehensive set of keyboard shortcuts to streamline editing tasks. Use Ctrl+Shift+A to select all text in the current file, Ctrl+F to search within the file, and Ctrl+R to perform a project-wide search. For quicker navigation, use Ctrl+B to go to a specific class or file, and Alt+Up or Down to scroll through the history of edited files.

Navigation Shortcuts

Navigate through code swiftly with keyboard shortcuts. Press Ctrl+N to open the navigation bar and search for classes, methods, or files. Utilize F2 to quickly jump between declarations and usages, and Ctrl+H to perform hierarchical structure navigation. Use Ctrl+E to open the Recent Files list and access frequently accessed files.

Refactoring with Precision

IntelliJ IDEA provides powerful refactoring tools to enhance code quality. Use Ctrl+Alt+Shift+T to refactor a variable, and Ctrl+Alt+Shift+M to extract a method. For renaming, simply press Ctrl+R+F. Utilize Ctrl+Alt+Shift+C to convert a class to an interface or vice versa, enhancing code flexibility and maintainability.

Debugging with Ease

Quickly and efficiently debug your Java applications. Set breakpoints with F9, step through code with F7, and step into a method with F8. Use Ctrl+D to view the current stack trace, and Ctrl+Alt+F to switch between debugger views. For advanced debugging, use Ctrl+Alt+S to open the Evaluate Expression window and execute code snippets on the fly.
