Windows10 上的安裝配置
1、前往 JDK 官網下載對應 jdk 版本安裝包：
本文以 jdk-8u161-windows-x64.exe 為例；
![75a1bb23-2528-4336-8918-d626eb51d57d[5]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQwMTcwMDUtNzQzODU1Mzk0LnBuZw==.png "75a1bb23-2528-4336-8918-d626eb51d57d[5]")
2、雙擊執行安裝包程序；
![9edaa71d-ab22-432e-b1ff-c91d0af2200a[5]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQwMjk1NzctMTcxNDg3NTEyOC5wbmc=.png "9edaa71d-ab22-432e-b1ff-c91d0af2200a[5]")
3、選擇需要安裝的可選功能；
![9b7685f9-5e4a-46c5-a00f-2669ef563d33[5]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQwMzkxNjUtMzYwODk5MTI0LnBuZw==.png "9b7685f9-5e4a-46c5-a00f-2669ef563d33[5]")
4、開始安裝；
![3f6e1df8-19ae-4e55-a033-3c048af0776f[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQwNDIzMzctMTQxNDM1MTU4My5wbmc=.png "3f6e1df8-19ae-4e55-a033-3c048af0776f[4]")
5、中間彈窗需要安裝 JRE；
![7df75b92-029c-4643-b99d-8c5c95b570af[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQwNTI1MjEtMjExODA5MDY4NC5wbmc=.png "7df75b92-029c-4643-b99d-8c5c95b570af[4]")
6、開始安裝 JRE；
![eab32f46-7687-4173-8678-20541b52cf76[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQxMDYzMzctMTcyMTE1MjYzNi5wbmc=.png "eab32f46-7687-4173-8678-20541b52cf76[4]")
7、程序安裝完成。
![7c8c1a23-df54-4f19-9fb7-fb4bd71e360e[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQxMTQwNzQtMTk3MzM5ODA3LnBuZw==.png "7c8c1a23-df54-4f19-9fb7-fb4bd71e360e[4]")
8、環境變量配置；
在"我的電腦"-"屬性"-"高級系統設置"-"環境變量"中增加環境變量；
![3dda66bd-b572-400e-8af4-024c81abcb29[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQxMjAxNzYtMTAzMDIzNTYzMy5wbmc=.png "3dda66bd-b572-400e-8af4-024c81abcb29[4]")
增加如下圖所示的兩個變量，和 PATH 追加的內容；
![f274c974-5119-4105-9ff6-e97e1e9ab470[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQxMjY3ODQtMjE3NTg5NTI1LnBuZw==.png "f274c974-5119-4105-9ff6-e97e1e9ab470[4]")
9、完成以上安裝及配置后，進入命令提示窗口中進行驗證；
java -version 命令查看當前 JDK 版本：
![4d8a8894-7126-4f0d-9018-cb7f59be6d67[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQxMjk2MTUtOTk0MzgxNjk5LnBuZw==.png "4d8a8894-7126-4f0d-9018-cb7f59be6d67[4]")
java 命令，查看命令用法；
![a0a8242c-4dd9-405c-97f4-dca7d0523b88[4]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQxMzc4ODUtODYwNDQyMTA5LnBuZw==.png "a0a8242c-4dd9-405c-97f4-dca7d0523b88[4]")
javac 命令，查看命令用法；
![045c1bf0-02f8-43db-9fd4-66f2bd5be69c[5]](/image/aHR0cHM6Ly9pbWFnZXMyMDE4LmNuYmxvZ3MuY29tL2Jsb2cvMzM1Mjg0LzIwMTgwMy8zMzUyODQtMjAxODAzMjcyMDQxNTcwNjMtOTc2NTAxNzM3LnBuZw==.png "045c1bf0-02f8-43db-9fd4-66f2bd5be69c[5]")
至此，Windows 系統下的 Java（JDK）環境配置完成！！
