如何在记事本中运行java代码？

用记事本写完代码后运行方法如下：

1、用浏览器打开用记事本编写的代码

新建“文本文档”后，鼠标右键点击该文本文档，在菜单栏的“打开方式”选择“用记事本打开”，也可以设置默认打开方式为“记事本”；用记事本打开文本文档后，直接在该文档内根据自己的需要输入想要编辑的网页代码。

2、记事本写java代码怎么运行

首先，需要安装jdk并配置环境变量。然后，在命令行中，用javac命令编译用记事本编写的代码。下一步，在命令行中，用java命令执行编译后的结果。

代码是什么

代码是程序员用开发工具所支持的语言写出来的源文件，是一组由字符、符号或信号码元以离散形式表示信息的明确的规则体系。代码设计的原则包括唯一确定性、标准化和通用性、可扩充性与稳定性、便于识别与记忆、力求短小与格式统一以及容易修改等。

计算机源代码最终目的是将人类可读文本翻译成为计算机可执行的二进制指令，这种过程叫编译，它由通过编译器完成。源代码就是用汇编语言和高级语言写出来的地代码。目标代码是指源代码经过编译程序产生的能被 cpu直接识别二进制代码。

可执行代码就是将目标代码连接后形成的可执行文件,当然也是二进制的。

Q4: 如何用java编写日历记事本

源代码都知道了，那不叫编写，应该叫运行。

1.打开一个记事本（windows里面自带那个）

2.复制过去，保存为xxx.java（xxx是带main方法的那个类名）

3.到sun网站下载一个JDK安装包进行安装

4.打开一个cmd窗口，进入保存xxx.java的目录，打入编译命令javac xxx.java

编译完成后（源代码没问题就会编译通过）,打入运行命令 java xxx.java

5.正常的话得到一个日历记事本窗口

貌似这是java第一章讲的内容，我汗
