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?

  1. 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。
  2. 有丰富的插件支持,可以满足各种项目的需求。
  3. 支持自动化构建、测试和部署,可以提高开发效率。
  4. 提供了强大的调试工具,可以快速定位和解决问题。
  5. 支持多版本控制系统,如Git、SVN等
  6. 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

1. 下载IntelliJ IDEA

IntelliJ IDEA支持Windows、macOS、Linux,根据自己的操作系统下载即可。

4. 新建项目

image-20231227165547054

设置项目名、项目存放地址以及JDK版本(由于作者电脑安装了JDK1.8和JDK17所以这里就有两个JDK版本)

image-20231227170313745

运行程序:右键——Run

image-20231227171049444

5. 基础设置

5.1 设置字体大小

file->Settings->Editor->Font

image-20231227171425421

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。

image-20231227171946941

5.3 忽略文件

file->Settings->Editor->file Tyes ->lgnores and Folders

*.dea*iml.idea.iml

image-20231227172431045

5.4 方法分割线

file->Settings->Editor->General->Appearnce->show method separstors

image-20231227172928724

5.5 询问文件

image-20231227174337434

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

  1. 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

  2. 彩虹颜色括号:Rainbow Brackets

  3. 阿里代码规约检测:Alibaba Java Coding Guidelines

  4. 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

虫子

image-20240104111431564

快捷键操作
F8单步调试(不进入函数内部)
F7单步调试(进入函数内部)
shift + F7选择要进入的函数
shift + F8跳出函数
alt + F9运行到断点
alt + F8执行表达式查看结果
F9继续执行,进入下一个断点或执行完程序
编程小号
