Java learning : how many classes defined in java source, how many .class byte code files will be generated after compile via javac

By 三好Daddy - March 26, 2020

One java source file generate one .class byte code file ? False. I thought one java source code file will generate only one .class byte code file, since I am a c++ programmer for about 10 years. The correct answer is how many classes defined in java source, how many .class byte code files will be generated after compile via javac public class HelloWorld { class HelloInternal { } } enum HelloEnum { } interface HelloInterface { } javac HelloWorld.java ls *.class HelloEnum.class HelloWorld$HelloInternal.class HelloInterface.class HelloWorld.class Java classes The classes can be any class, interface and enum. All java codes should be placed in the classes. otherwise you will get compile error class, interface, or enum expected In fact, enum is a class too, just a syntactic sugar.
