一.Java项目创建

1、打开idea软件，点击界面上的Create New Project

2、出现以下界面，选中Java，然后选择jdk，最后点击Next，进行下一步（我的是jdk1.8）

3、接下来的界面是询问是否从模板中创建java项目，可以不选。

4、指定项目的存储目录及项目名称，默认是'untitled',建议修改下

5、项目创建完成

注意：IDEA的java项目(Project)则相当于Eclipse的工作空间(workspace)的概念。

二、HelloWorld

1、创建package

点击src ——> new ——>package，创建一个文件包，并给包命名，与Eclipse的包类似

多级package通过'.'连接

2、创建java文件

在包下面创建java类文件，点击包名——>New——>Java Class;

3、执行程序

常用的快捷方式

运行java文件，点击Run——>Run

运行结果

ok~idea的简单使用介绍到此。
