+- ## 总结
+  collapsed:: true
+	- 1. Java跨平台原理
+		- Java程序运行在JVM虚拟机上,通过不同平台上的不同的JVM做到跨平台
+	- 2. IDE集成开发工具
+		- 常见工具
+			- Eclipse,IDEA
+		- IDEA的下载安装
+		- IDEA新建项目
+			- Create-->Java--> Create project from template
+			  Project name
+			  Project location
+			- ((6243a9f6-b334-4daf-b1ec-b51335bba244))
+				- com 公司
+				  gov 政府
+				  edu 教育
+				  org 开源
+				- 公司组织名称
+				- 项目名称
+		- IDEA设置调整
+			- 字体大小
+			- 背景修改
+			- 设置Eclipse快捷键
+			- Eclipse快捷键
+	- 3.标识符
+		- 系统默认标识符,称为关键字
+			- 共50个
+			- goto const不常用
+			  true false null为保留关键字
+		- 自定义标识符
+			- 组成:数字,字母,_,$
+			  不以数字开头,区分大小写
+			  不能为关键字
+			- 命名原则:
+			  类名使用大驼峰
+			  方法名,变量名,参数名使用小驼峰
+			  常量名单词大写,用_分割
+	- 4. 变量
+		- 3种注释
+			- 单行
+			  ```java
+			  //单行注释
+			  ```
+			- 多行
+			  ```java
+			  /*
+			   *多行
+			   *注释
+			   */
+			  ```\
+			- 文档
+			  ```java
+			  /**
+			   *文档
+			   *注释
+			   */
+			  ```
+		- 变量是在一定范围内可以变化的量
+			- 两种变量声明
+			- 分类:
+				- 全局变量
+				- 局部变量
+			- 注意:
+				- 定义后必须赋初值
+				- 同一方法内不能重复
+		- 常量
+			- 恒久不变的量
+	- 5. 基本数据类型
+		- |byte|short|int(默认整数)|long|float|double(默认浮点)|char|boolean|
+	- 6. 隐式转换
+		- 小容量数据向大容量数据自动向上转换
+		- 字符集
+			- ASCII码
