Java Reflection Made Easy<\/h2>\n

\njava<\/strong>(at sentence-end, falling tone) indicates a confident conclusionreflection<\/strong>Introducing utility classes for easy access to the API.\n<\/p>\n

What is reflection?<\/a><\/h2>\n

\nReflection API<\/strong>is the \"thejava.lang.reflect<\/strong>\u201d included in the package,
\nThis is an API that retrieves information such as fields and methods from Java classes.
\nThe following classes are mainly used.\n<\/p>\n

    \n
  • Class<\/strong><\/li>\n
  • Constructor<\/strong><\/li>\n
  • Method<\/strong><\/li>\n
  • Field<\/strong><\/li>\n<\/ul>\n

    \nreflection<\/strong>By using , you can create classes or call methods without having to code them directly.
    \nYou can create a class instance from a string or execute a method.<\/p>\n

    By writing the definitions of class names and method names in external files such as XML, you can dynamically adapt the application to changes in the environment during runtime.
    \nIt is also a very effective API for building highly flexible applications.\n<\/p>\n
