本篇文章重点说明什么是函数柯里化,这个语法现象的背后动机是什么,有什么样的应用场景,以及与部分应用函数(Partial Applied Function)之间的联系 1. 什么是柯里化函数
A way to write functions with multiple parameter lists. For instance
def f(x: Int)(y: Int) is a
ApplicationContext能读取多个Bean定义文件,方法是:
ApplicationContext appContext = new ClassPathXmlApplicationContext(
new String[]{“bean-config1.xml”,“bean-config2.xml”,“bean-config3.xml”,“bean-config4.xml

但是用java来实现有一个问题。
由于Java无法像C那样“传递参数的地址,函数返回时能得到参数的值”,唯有新建一个辅助类:AuxClass
import ljn.help.*;
public class BalancedBTree {
BeanUtils.copyProperties VS PropertyUtils.copyProperties
作为两个bean属性copy的工具类,他们被广泛使用,同时也很容易误用,给人造成困然;比如:昨天发现同事在使用BeanUtils.copyProperties copy有integer类型属性的bean时,没有考虑到会将null转换为0,而后面的业
