技术/工具/IDEA 学习笔记
IDEA基础功能概览：
-
shortcut(edit, 代码片段, 功能), 版本控制(VCS: git, github, local history)
-
Debug, javadoc generator, database, web deployment
-
project&module 等概念, 模板, 项目结构查询管理
Tips
- 代码段：main
- sout标准输出
- soutv输出变量，soutm输出方法名，soutp输出命令行参数
- 变量名.sout输出变量
- iter增强型for循环
- 引用名.for 迭代指定引用类型
- 实例名.fori顺序遍历 xxx.forr倒序遍历
- ifn --“if xxx is null”, inn --“if not null”
- xxx.nn, xxx.ifn
- JavaLea
- 条件断点 --右键断点处
- ctrl+u 查看表达式的值
- Tools javadoc generator:
- Local: zh_CN; Other command line args: encoding UTF-8 -charset UTF-8
