推荐答案

.class文件是一个编译的.java文件。

A .class file is a compiled .java file.

.java是所有文本，并且是人类可读的。

.class是二进制（通常）。

.java is all text and is human readable.
.class is binary (usually).

通过转到命令行，导航到.java文件并运行

You compile a java file into a class file by going to the command line, navigating to the .java file, and running

javac "c:\the\path\to\your\file\yourFileName.java"

您必须在计算机上安装一个java SDK（从 Oracle ），并确保javac.exe文件位于计算机的PATH环境变量中。

You must have a java SDK installed on your computer (get it from Oracle), and make sure the javac.exe file is locatable in your computer's PATH environment variable.
