java - Read property of an annotation in another -

if declare attribute class way:

@order(value=1) @input(name="login") private string login; 

and definition @input this:

@retention(retentionpolicy.runtime) @target(elementtype.field) public @interface input {      string type() default "text";     string name();     string pattern() default "";      string tag() default "<custom:input ordem=''/>";  } 

is there way read property value @order , use property tag @input?

one of ways of reading metadata such annotations,fields , classes reflection.you can use reflection read meta -data of annotation too.

this work if @order annotation has runtimepolicy of runtime @retention(retentionpolicy.runtime)

note :- annotations class objects.each annotation special type of interface , interfaces treated java.lang.class objects.

field loginvariaable = .../// login attribute class object using reflection  order order = loginvariaable.getannotation(order.class) int ordervalue = order.value();  input inputobject = loginvariaable.getannotation(input.class) string inputname= inputobject.name(); 

generics helps in getting annotation object without casting annotation object.also ,note annotations implicitly extends java.lang.annotation.annotation
