.Class files are the files that store the JAVA byte code. The byte code generated by Java is compiled by a Java compiler using the JVM (Java virtual machine environment), which compiles this high level byte code into assembly language code.
If the .CLASS file has more than one CLASSes defined in the program, the compiler will create separate CLASS files automatically when the code is compiled. One of the reasons why .CLASS files are popular is because they make the code written in Java, platform independent. This means that a .CLASS file generated on one platform can be run on other platform.
