package cn.xnip;
import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;
import java.lang.annotation.Annotation;
import java.lang.reflect.AccessibleObject;
public class AccessibleObjectDemo {
   public static void main(String[] args) throws NoSuchMethodException, 
      SecurityException, NoSuchFieldException {
         AccessibleObject sampleField = SampleClass.class.getDeclaredField("sampleField");
         System.out.println("sampleField.isAccessible: " + sampleField.isAccessible());
   }
}
@CustomAnnotation(name = "SampleClass",  value = "Sample Class Annotation")
class SampleClass {
   private String sampleField;
   @CustomAnnotation(name = "sampleMethod",  value = "Sample Method Annotation")
   public String sampleMethod(){
      return "sample";
   }
   public String getSampleField() {
      return sampleField;
   }
   public void setSampleField(String sampleField) {
      this.sampleField = sampleField;
   } 
}
@Retention(RetentionPolicy.RUNTIME)
@interface CustomAnnotation {
   public String name();
   public String value();
}

让我们编译并运行上面的程序，这将产生以下结果 -

sampleField.isAccessible: false
