推荐答案

.class 文件是编译后的 .java 文件.

A .class file is a compiled .java file.

.java 都是文本，是人类可读的.
.class 是二进制的(通常).

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

您可以通过转到命令行、导航到 .java 文件并运行将 java 文件编译为类文件

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"

您的计算机上必须安装了 Java SDK(从 Oracle)，并确保 javac.exe 文件可在您计算机的 PATH 环境变量中找到.

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.
