Nature annotations

• Annotations is the nature of the interface can be verified by the following code:

public class Test {

    public static void main(String[] args) {
        Class clazz=Anno02.class;
        System.out.println("是否是接口");
        System.out.println(clazz.isInterface());//true
        System.out.println("===========继承那个接口=============");
        Class[] cs=clazz.getInterfaces();
        for (Class class1 : cs) {
            System.out.println(class1);// java.lang.annotation.Annotation 
        } 
        the System. OUT .println ( " ========== ============ Method " );
         / * * 
         * See reflection time the method is to annotation property: 
         * abstract public java.lang.String cn.edu.xcu.annotation.v2.Anno02.m () 
         * / 
        method, [] MS = clazz.getMethods ();
         for (method, method: MS) { 
            . the System OUT .println (Method); 
        } 
        . the System OUT .println ( " ========== field ============ " ); 
        field, [] FS =clazz.getFields();
        for (Field field : fs) {
            System.out.println(field);
        }
    }
