How to compile a java project with a terminal/cmd
提问by zin
I got tired of using Eclipse because it was too "plain" and "old style". So I moved on to a program called Sublime Text 3 and I used a package named "material theme" which made the program look flat and all nice and stuff.
我厌倦了使用 Eclipse，因为它太“简单”和“老式”了。所以我转向了一个名为 Sublime Text 3 的程序，我使用了一个名为“材料主题”的包，它使程序看起来很扁平，而且一切都很好。
But I wanted to code Java in that but I don't know how to compile stuff without using an IDE and it was not easy to find out but I found out that you could do it through the terminal/cmd of your operating system.
但我想在其中编写 Java 代码，但我不知道如何在不使用 IDE 的情况下编译东西，而且不容易找到，但我发现您可以通过操作系统的终端/cmd 来完成。
But what I don't understand is how I could actually use the javaccommand which means Java Compile and I searched and I didn't find out because I couldn't understand anything that was posted on either YouTube or Stack Overflow because I'm new to this whole terminal/cmd Java Compiling thing.
但我不明白的是我如何实际使用该javac命令，这意味着 Java Compile 并且我进行了搜索但我没有找到，因为我无法理解发布在 YouTube 或 Stack Overflow 上的任何内容，因为我是新手到整个终端/cmd Java 编译的东西。

You're almost there buddy!
你快到了，伙计！
Just be sure you have the Java Development Kit (JDK)installed in your system. The JDK provides you the command javac-which you need to compile your .javaprogram files.
只要确保您Java Development Kit (JDK)的系统中安装了 。JDK 为您提供了javac编译.java程序文件所需的命令。
The javaccommand is not that friendly as you think it is. You have to let it know where to find the java file you want to compile.
该javac命令并不像您想象的那么友好。您必须让它知道在哪里可以找到要编译的 java 文件。
For example you saved Main.javainside C:\Projects\Javayou must compile it this way javac C:\Projects\Java\Main.java.
例如你保存Main.java在里面C:\Projects\Java你必须这样编译它javac C:\Projects\Java\Main.java。
Then you can run your program this way too java C:\Projects\Java\Main
然后你也可以这样运行你的程序 java C:\Projects\Java\Main
As mentioned here... You can find a more detailed explanation to the official tutorial.

You did not install JDK. You need to install JDK which has javac command.
你没有安装JDK。您需要安装具有 javac 命令的 JDK。
Installing JDK on MAC instructions
Installing JDK on Windows instructions
After installing JDK(Java Development Kit), you can run the command javac -versionon command line and let it show the version that is installed.
安装JDK（Java Development Kit）后，您可以javac -version在命令行上运行该命令并让它显示已安装的版本。
