java反射获得方法的返回值类型，,package cn.o

package cn.outofmemory.snippets.core;public class GetReturnType {    public static void main(String args[]){        Class<?> clazz = java.lang.ThreadLocal.class;        Method[] methods;        // return class and super class methods        methods = clazz.getDeclaredMethods();        for (int i = 0; i < methods.length; i++){            System.out.println(methods[i] + ", return type :" + methods[i].getReturnType());        }     }}

输出：
