An entry that tells me about my uncle's favorite ** IntelliJ IDEA **.
It's my first time to put * gif, and I feel a lot of disappointment. I'll fix it someday. *
Czech-based ** JetBrains IDE ** (Integrated Development Environment) for Java. It features powerful input completion and refactoring functions, and is said to be the most popular Java development environment in the 2016 survey.
There is a paid version of IntelliJ IDEA Ultimate and a free and open source IntelliJ IDEA Community. Android Studio, which is the official Android IDE, is also based on IntelliJ IDEA because it is open source, and it has the same usability and so on. Recently, Android Studio has joined the JetBrains Toolbox, which allows you to centrally manage the JetBrains IDE.
IntelliJ IDEA is for Java, but there are also Rider for .NET languages such as C # and PhpStorm for PHP. Both are charged (reasonably expensive). There is a free version of PyCharm for Python. Use it?
If you are a student, you can use everything for free. The magical ** student license is fairly easy to obtain **, so please try it.
I personally like the following four points
--Can be used on Win / Mac / Linux --Easy to build environment --Git etc. are supported by IDE --The function that generates constructors etc. is the best
You have to install a plug-in like Visual Studio Code ... or something like that, and if you install it, you can use it immediately. Since it is automatically saved when you make changes to the source file, it is common in Visual Studio (I think) I forget to save → Build does not occur.
Once you get used to IntelliJ IDEA, you'll have to do this, so I hope everyone will.
--Slow startup ――Slightly heavy --Japanese is not supported
Overcome with machine power and spirit.
Java execution environment and JDK are required as prerequisites for running IntelliJ IDEA, so please install them.
You can install only IntelliJ IDEA, or you can install it from JetBrains ToolBox, which allows you to centrally manage the JetBrains IDE.
You can install IntelliJ IDEA alone by downloading it from here. If you start the installer, you should be able to install it properly.
With JetBrains ToolBox, you can easily install, launch, and update your IDE. Project files opened in the JetBrains IDE are also listed, saving you the trouble of searching for them in Explorer and double-clicking them. Also, since I notice that the update is coming before starting the IDE, ** "I wonder if I have to update and restart even though I started it, I'm withered" phenomenon ** is unlikely to occur. The best.
You can download it here. If you start the installer, you should be able to install it properly.
After installing Toolbox, install IntelliJ IDEA Community from ʻAVAILABLE TOOLS`.
The paid version is also listed, but if you use it for a month, you will be forced to purchase it, so install the free version quietly. I've used both Community and Ultimate, but the free version does the basics without any inconvenience. You did it!
Hello, IntelliJ IDEA. When you start IntelliJ IDEA, you will be asked something like ** "I ... white is better? Black is better?" **, so please choose the one you like and proceed steadily. Do you have any additional add-ons? But you can add it later and it works normally, so don't put anything in it and go to the next.
Then, it will look like the top page, so click ** Create New Project **.
For the time being, select Java and Next. The next screen is also Next without any particular tweaking. On the next screen, select the project name and directory of your choice and Finish.
You can see the file tree in the
Project tab in the upper left.
Here, create class files and directories.
Let's try creating a Java class file.
You can create a class file by right-clicking on the
src directory under the project directory and selecting
New> Java Class.
When you create a class file, an editor will appear on the right. I will write a program here.
Let IntelliJ IDEA write the code. Choose
Code> Generate from the stripe menu or use keyboard shortcuts.
Ctrl + Alt + Insert for Windows / Linux,
⌘ + N for Mac.
Right? Is it convenient? In addition to the constructor, you can also generate override methods and getters / setters.
You can jump to the method pointed to by the cursor. Hold down the Ctrl key on Windows / Linux and the ⌘ key on Mac and click the method name or class name you want to jump to.
If you're wondering what this guy is doing ...?, You can easily go see it with this.
Shift + F6, you can change variable names, method names, class names, etc., including all dependencies.
You can fix embarrassing Typo right away.
You can add a breakpoint by clicking just next to the line number. If you debug with this, you can stop the operation at that line and see the value of the variable in that state.
Right-click and select
Debug to debug.
I wonder if it will be useful when I am suffering from an incomprehensible error. Step execution can also be done with NetBeans.
When using Git etc., you can do it from
VCS in the stripe menu.
To execute it, right-click the file with the
main () method in the editor and select
Run to build and execute it.
By mastering IntelliJ IDEA, you can program faster, more accurately, and more comfortably. Please use it by all means.
