java - no suitable method found for getAnnotation(Class<CAP#1>) -

i'm coding few simple methods annotations class, field, or method. first method, gets class-level annotation, works fine. copy , paste create new method field-level annotation results in compile error saying:

error: no suitable method found getannotation(class<cap#1>) 

not sure how getannotation method call on class object works ok same method call on field object results in compilation error.

thoughts?

public class annotationtool {     public static <t> t getannotation(class c, class<? extends t> annotation) {         return (t)c.getannotation(annotation);     }      public static <t> t getannotation(class c, string fieldname, class<? extends t> annotation) {         try {             field f = c.getdeclaredfield(fieldname);              return (t)f.getannotation(annotation);   // compile error here??         } catch (nosuchfieldexception nsfe) {             throw new runtimeexception(nsfe);         }     } } 

field.getannotation expects class subclass of annotation:

public <t extends annotation> t getannotation(class<t> annotationclass) { 

therefore in helper method need restrict type parameter accordingly:

public static <t extends annotation> t getannotation(class<?> c, string fieldname, class<t> annotation) { 

note same holds class level helper method. used raw type class c prevented compiler issue same error.
