IDEA sets itself apart from other products by offering incredibly advanced ways to find objects and files within large projects. Make this pane more useful by tweaking the configuration options: Leaving this pane open helps you quickly locate the desired point within a class. Structure Pane: Shows the structure of the active file, including methods, properties, and inner classes. Sorts the Java classes by type from the most abstract to the most concrete Shows the methods and properties of objects within the Project pane Shows the Structure pane (explained next) as a window nested within the Project pane When an item is opened in the Editor pane, that item is scrolled to in the Project pane When an object or method is clicked in the Project pane, that item is opened in the Editor pane. Properly configuring the Project pane makes it more effective: In version control (object name appears black, or blue if edited) Not in version control (object name appears in red) Test Case (indicated by red and green triangles) Objects in the project view visually indicate their type with an icon (which also appears on the editor tabs).įind objects faster by learning what the icons mean:Ĭlass with main( ) (indicated by green triangle) Project Pane: Shows the contents of the current project, allowing you to view the project as files, packages, or scopes (more about this later). Effectively using this can greatly speed up bulk edits on structured data like SQL or csv files This is supported across many languagesĬolumn mode allows you to select a rectangular fragment of code. Sets or removes a bookmark on the current line, which shows as blue in both the left and right gutterĬomments out current selection, or removes comments from from current selection. Experiment to learn how this works differently depending on where your cursor starts Quickly select or unselect the word, statement, block, and method by repeating this action. Selects and unselects the word at the caret. Use Ctrl+Shift+V to paste from a previous copy instead of the most recent clipboard contents When copying text, IDEA remembers your previous copies.
When nothing is selected, copy, cut, and paste operate on the entire line Moves the current selection down one line in the file Moves the current selection up one line in the file The KeyPromoter plugin can help you with this.Įdit faster by learning these commands: Move Statement Up If you're switching to IDEA from another tool, consider learning the new bindings rather than loading an alternate key map. The mouse is slow: stop using it! The IDEA key bindings have received praise over the years, and many believe they are simply better than other IDE's default bindings. Toolbar icons are shown throughout this guide, but you'll be much faster if you learn the key bindings. Navigate faster by learning these commands: Edit faster by learning these commands: BackĪctivate tab to the right of the active oneĪctivate tab to the left of the active one IDEA supports syntax highlighting for many languages, but is also language aware and shows syntax errors as they occur. Also, there is seldom a need to save a file file saving is performed automatically in the background. If the maximum number of tabs is reached, then the oldest tab is closed when a new tab is opened. IDEA shows the most recently used files in the tabs, and there is seldom a need to manually close tabs.

The three most important elements of the IDE are the Editor pane (a), where your code is shown, the Project pane (b), where your project's contents are shown, and the Structure pane (c), where the details of the open object are shown.Įditor Pane: Shows the currently active file, with recently viewed files in the tab bar.
