Java Environment installation (Win7)

First of all, you should have installed the Java JDK, the author installed is: jdk-7u13-windows-x64

Next the main talk about how to configure the environment variables of Java, but also for the next day I forgot to make a backup

1. Go to the "Properties" option of "Computer" and select "Advanced system Settings" as shown in:

2. When you click on "Advanced system Settings", you will see the dialog box as shown, select "Environment variables":

3. After clicking on "Environment variable", you will see the dialog box as shown:

4, the next step is the specific configuration process:

①、选择所示的“新建”，

“变量名”：Java_Home“变量值”：D:\Program Files (x86)\Java\jdk1.7.0_67注：“变量值”这一栏主要填写的是你安装 java 的路径，这里根据个人的情况可能会有所不同②、上步结束之后，选中环境变量中的“path”，如所示：

选中之后编辑：在“变量值”一栏的最前面添加如下的 code：%Java_Home%\bin;%Java_Home%\jre\bin;注意：上面的代码最好一个字符不要差，因为 Java_Home 已经限制了你的 JDK 的路径了，Java 的每个版本的 JDK 应该都是由这些东西构成的③、上一步确定之后，再“新建”：

“变量名”：ClassPath“变量值”：.;%Java_Home%\bin;%Java_Home%\lib\dt.jar;%Java_Home%\lib\tools.jar注：上面的代码最好也是一个字符不变的贴上去，“变量值”最前面的 .; 不要漏掉。

After completing the three steps above, the configuration of the environment variable has been completed.

5, check whether the environment variables are set up: "CMD" check

1、输入：“java”，你应该看到下面的东西：![这里写图片描述](http://img.blog.csdn.net/20160419104535113)2、输入“javac”，你应该看到下面的东西：

3、输入“java -version”，你应该看到下面的东西：

If you see the three pictures above, congratulations, the Java environment variable is configured!
