Recently I bought a new desktop system and installed Windows 7 Ultimate 64-bit on it. Being a Java Developer, the first thing I did after the regular setup is to download and install [JDK][].

最近，我购买了一个新的台式机系统，并在其上安装了Windows 7 Ultimate 64位。 作为Java开发人员，常规设置后我要做的第一件事是下载并安装[JDK][] 。

I was using Windows XP, Solaris, or Mac OS for my development purpose till now. I was installing Java for the first time on Windows 7 64-bit OS.

到目前为止，我一直使用Windows XP，Solaris或Mac OS进行开发。 我是在Windows 7 64位操作系统上首次安装Java。

**Step 2**: Unzip the downloaded ZIP file (**jdk-14.0.1**) and copy it to the program files folder.

**步骤2** ：解压缩下载的ZIP文件（ **jdk-14.0.1** ），并将其复制到program files文件夹中。

**Step 3**: Setting up environment variables so that we can execute java commands from the command prompt.  
  
For this, go to Control Panel > System > Advanced system settings. In the “System Properties” pop up, go to the Advanced tab and click on the “Environment Variables” button.  
  
In the System Variables section, we have to set **JAVA\_HOME and edit the** Path variable. Variable name and values are:  
  
**JAVA\_HOME=C:\\Program Files\\jdk-14.0.1**  
  
Add “;%JAVA\_HOME%\\bin” to the Path variable. Click on the Ok button to save it.

**步骤3** ：设置环境变量，以便我们可以从命令提示符处执行Java命令。  
  
为此，请转到控制面板>系统>高级系统设置。 在“系统属性”弹出窗口中，转到“高级”选项卡，然后单击“环境变量”按钮。  
  
在系统变量部分，我们必须设置**JAVA\_HOME并编辑** Path变量。 变量名称和值是：  
  
**JAVA\_HOME = C：\\ Program Files \\ jdk-14.0.1**  
  
将“;％JAVA\_HOME％\\ bin”添加到Path变量。 单击确定按钮将其保存。

**Step 4:** Now we can run java commands from the command prompt. You can check it by executing the “`java -version`” command. It will print the current Java version.

**步骤4：**现在我们可以从命令提示符下运行Java命令。 您可以通过执行“ `java -version` ”命令进行检查。 它将打印当前的Java版本。

## 重要事项 **(****Important Points****)** ##

*  From JDK 12 onwards, Oracle JDK requires a license to use in production and commercial applications. So, if you want to use Java free of cost, use OpenJDK.
    
    从JDK 12开始，Oracle JDK需要许可证才能在生产和商业应用程序中使用。 因此，如果您想免费使用Java，请使用OpenJDK。
 *  If you need paid support, then you can use OracleJDK and opt for their paid license.
    
    如果您需要付费支持，则可以使用OracleJDK并选择其付费许可。
