0. 前言

工欲善其事必先利其器，作为一名Java开发者，手上必须得有趁手的工具。市面上的Java开发IDE有：Eclipse、NetBeans、Lightly、IntelliJ IDEA、JDeveloper 。

作者推荐使用IntelliJ IDEA，为什么推荐它呢？

提供了强大的代码编辑功能，包括代码补全、语法高亮、代码重构等。
有丰富的插件支持，可以满足各种项目的需求。
支持自动化构建、测试和部署，可以提高开发效率。
提供了强大的调试工具，可以快速定位和解决问题。
支持多版本控制系统，如Git、SVN等
可以与其他开发工具（如Maven、Gradle等）无缝集成，方便开发者进行项目管理。

PS:安装IDEA之前需要安装JDK，JDK安装教程

最简单IntelliJ IDEA安装教程（小白也能一次性安装完成）,工具环境安装,Java,intellij-idea,java,ide

个人建议把字体大小设置为18，显示器最好能看30行代码。

5.2 鼠标滚轮调整字体大小

file->Settings->Editor->Change font size with Ctrl + Mouse Wheel in，勾选Change font size with Ctrl + Mouse Wheel in选项即可。

6. 常用快捷键

快捷键组合	实现效果
psvm + Tab键 / main + Tab键	public static void main(String[] args)
sout + Tab键	System.out.println()
Ctrl + X	删除当前行
Ctrl +D	复制当前行
Alt+Insert(或右键Generate)	生成代码(如get,set方法,构造函数等)
Ctrl+Alt+T	生成try catch （或者 Alt+enter选择）
CTRL+ALT+T	把选中的代码放在 TRY{} IF{} ELSE{} 里
Ctr+shift+U	实现大小写之间的转化
ALT+回车	导入包,自动修正
CTRL+ALT+L	格式化代码
CTRL+ALT+I	自动缩进
CTRL+E	最近更改的代码
fori	生成for (int i = 0; i < ; i++) {}
Alt + <–左右–>键	实现窗口左右更换（多窗口）
Ctrl + 鼠标点击	快速找到成员变量的出处
Shift+F6	重构/重命名 (包、类、方法、变量、甚至注释等)
CTRL+Q	查看当前方法的声明
Ctrl+Alt+V	自动创建变量（new 对象();之后选择按快捷键）
Ctrl+O	重写方法
Ctrl+I	实现方法
ALT+/	代码提示
Ctrl+Shift+R	在当前项目中替换指定内容
Ctrl+E	最近编辑的文件列表
Ctrl+P	显示方法参数信息
Ctrl+Shift+Insert	查看历史复制记录，idea可以保留历史复制的 100 条记录

7. 插件

CodeGlance

CodeGlance是一款代码编辑区缩略图插件，可以快速定位代码，使用起来比拖动滚动条方便多了
彩虹颜色括号：Rainbow Brackets
阿里代码规约检测：Alibaba Java Coding Guidelines
汉化插件：chinese（个人建议尽量不要汉化）

最后建议，插件宜少不宜多，选择最适合最需要使用的就行，不必贪多，否则可能会适得其反，IDEA会变得臃肿卡顿，反而影响开发效率。

8. IDEA 调试工具

IDEA 调试方式：首先需要设置断点，然后单击虫子按钮进入 DeBug模式。
