.java files are source files, while .class files are compiled (bytecode) classes.

Use <a href="https://docs.oracle.com/javase/1.5.0/docs/tooldocs/windows/javac.html" rel="nofollow noreferrer">javac</a> to compile source into bytecode.

A .java file contains your Java source code while a .class file contains the Java bytecode produced by the Java compiler. It is your .class files that run on the JVM to execute a Java application.

It is the .class files you will use when you deploy your applet.

.java usually holds your code in clear text

.class contains the byte code of your .java. Think of it as a compiled version of the .java file

blocks|key|1525984|text|Person可以定义为类person。该类应该驻留在一个Java源代码文件(Person.java)中。使用这个Java源代码文件，Java编译器(+Windows上的javac.exe或Mac+/Linux/UNIX上的javac+)生成字节码(为Java虚拟机编译的代码)并将其存储在Person.class中。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1525985|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

person can be defined as a class Person. This class
should reside in a Java source code file (Person.java). Using this Java source code file,
the Java compiler (javac.exe on Windows or javac on Mac OS X/Linux/UNIX) generates
bytecode (compiled code for the Java Virtual Machine) and stores it in Person.class.

Java files is an human readable language (for example, the code we write in Eclipse/any other IDE).

Class files are in byte-code compiled for Java Virtual Machine (JVM).

What's the difference between a .class file and a .java file? I am trying to get my applet to work but currently I can only run it in Eclipse, I can't yet embed in HTML.
Thanks

**Edit: How to compile with JVM then?

.class vs .java

虚拟机

编译器

Windows

Eclipse

Linux

Java

.class文件和.java文件有什么不同？我正在尝试让我的applet工作，但目前我只能在Eclipse中运行它，我还不能嵌入到HTML中。谢谢**编辑:如何使用JVM编译？
