怎样利用JAVA反射技术查找一个类的所有属性

package cn;
import java.lang.reflect.*;
public class Test {
  private double d;
  public static final int i = 37;
  String s = "testing";
  public static void main(String args[]) {
   try {
      Class cls = Class.forName("cn.Test");
      Field fieldlist[] = cls.getDeclaredFields();
     for (int i = 0; i < fieldlist.length; i++) {
        Field fld = fieldlist[i];
        System.out.println("name = " + fld.getName());
        System.out.println("decl class = " + fld.getDeclaringClass());
        System.out.println("type = " + fld.getType());
       int mod = fld.getModifiers();
        System.out.println("modifiers = " + Modifier.toString(mod));
        System.out.println("-----");
      }
    } catch (Throwable e) {
      System.err.println(e);
    }
  }
}
