Then if I check all the files under that directory, then I will get the Main.java file as well. As my user name contains white spaces, I have used " " to enclose them. I need to use cd to indicate that I want to change directory. Or, if I want, I can also go there using my terminal. I can simply go there through my file explorer. Suppose I have the source code ( Main.java ) inside This PC > Documents folder. How to go into the directory where the source code is: for Windows □ You can go straight into the directory through your file manager if you want. If you have already written your Java code in an editor, then simply go into that directory. public class Main □ Step 1 – Go to the directory where your source code is I will be using the following Java code in the next step. The process I am going to show you in this article is applicable to any operating system whether that is Windows, MacOS, or Linux. Fear not! The procedure is quite easy, and after reading the entire article you should be able to run your own Java code in the terminal. In this article, I will show you how you can execute Java directly from your favorite terminal window. Whatever your purpose may be, executing Java code directly from the terminal is a very easy task. This gives them better clarity and helps them understand how the code is working, where it is returning the desired value, where the bug might be, and so on. Many of you might have heard that experienced professional programmers also use the terminal to execute the programs. However, it is good practice to know how your code actually executes and provides the output it gives you. Running code in your IDE is straightforward, but you don't often get to see how it executes your code (even though you can check the command in the terminal of course!). I usually prefer these to be shown.Ĭlicking on a variable highlights it throughout a file.If you work with Java, you've probably used one of the well known text editors like Sublime Text, VS Code, Brackets, Atom, and Notepad++ as well as IDEs like Apache NetBeans and IntelliJ IDEA. UI Show/hide the items along the edges of the IDEĬlick the icon in the bottom left-hand corner of the window to toggle the visibility of the edge items, like projects, Maven, etc. Simply right-click the file in the editor window, then select Local History -> Show History. You can also view local history for a file. It will show all changes made to all your files in chronological order, and you can revert back to any of them. Get to it by going to VCS -> Local History -> Show History. Local historyĭelete something on accident? Inadvertently get yourself into a pickle with git? Never fear, local history is your best friend. IntelliJ refers to this as the “Switcher” and it’s documented here. You can use the ← and → keys to expand and collapse folders in the tree in the Project view.Ĭycle through open files and tool windowsĬtrl + Tab lets you cycle through any processes you have open in the current session.

Show overview of current file, methods, etc. This removes any unused imports and consolidates multiple imports from the same packages based on a threshold (default 5, iirc) Go to symbol or method (On some keyboard layouts this is ⌘ + ⌥ + ⇧ + O) Go to file (On some keyboard layouts this is ⌘ + ⇧ + O) Go to class (On some keyboard layouts this is ⌘ + O) Jump to source (this can also be done by ⌘ + clicking on the code) It may be that I don’t have the feature activated that those correspond to.) Navigate code Command (I’m not sure why ⌘ + 8 doesn’t seem to activate anything, at least on my machine as I’m writing this. IntelliJ has a convention of ⌘ plus a number to pull up various IDE tabs. This menu is extremely useful for when you forget a hotkey (as long as you don’t forget the hotkey for the action menu itself). Just type in whatever action you’re looking for, whether that’s commenting your code or popping open a terminal. ⌘ + ⇧ + A activates the super-versatile Action Menu. I do all of my development work in IntelliJ on Mac, and this is a collection of tips, tricks, and shortcuts I use to get the most out of it. Useful IntelliJ hotkeys and workflows on macOS
