针对Java的开发工具,一般都有Compile、Make和Build三个菜单项,完成的功能的都差不多,但是又有区别。 编译,是将源代码转换为可执行代码的过程。编译需要指定源文件和编译输出的文件路径(输出目录)。Java的编译会将java编译为class 文件,将非java的文件(一般成为资源文件、比如图片、xml、txt、poperties等文件)原封不...

By default Java .class files do not store parameter names. To store parameter names in a particular .class file, and thus enable the Reflection API to retrieve parameter names, we need to compile the source file with the -parameters option of the javac compiler. Example...

javac<path_to_java_file> 1. 在上述命令中,<path_to_java_file>应替换为你要编译的Java源代码文件的路径。这将编译Java源代码并生成相应的.class文件。 现在你已经成功地实现了"Information:javac 8 was used to compile java sources"。你可以通过检查编译的输出结果来确认编译是否成功。
