The@Deprecatedannotation is used to mark a class, method or field as deprecated, meaning it should no longer be used. If your code uses deprecated classes, methods or fields, the compiler will give you a warning. Here is@DeprecatedJava annotation example: @Deprecated public class MyComponent {...

They do not change or affect the code by any meaning and they can be used by 3rd applications called consumers in order to analyze the code using reflection. We listed the built in annotations that are available per default in Java, some of them also called meta annotations like @Target ...
(see explanation below), such as the outer "this" parameter to an inner class constructor will be represented in the returned array. If the executable has no parameters (meaning no formal, no synthetic, and no mandated parameters), a zero-length array will be returned. If theExecutablehas ...
