在调试scala在线开发教程(http://www.imobilebbs.com/wordpress/archives/4911)的过程中看到了以下代码,但是这段代码无论怎么调试都无法成功. abstract class Element{ def contents:Array[String] val height:Int = contents.length val width:Int = if(height==0) 0 else contents(0).length } class Unifor
原文地址: http://www.cnblogs.com/ysdyaoguai/p/3746828.html In Unity scripting, there are a number of event functions that get executed in a predetermined order as a script executes. This execution order is described below: 在Unity脚本中,有一些按照预定顺序执行的事件函数,脚本即是
1.Car c = new Car(); Car c2 = new Car(); 1> c 和 c2之间的区别? public static void main(String[] args) { // TODO Auto-generated method stub Car c = new Car(); Car c2 = new Car(); System.out.println(c == c2); } } class Car{ int number = 4; String color = "
跟atexit函数相识已久,man手册里对atexit的解释是这么一段: The atexit() function registers the given function to be called at normal process termination, either via exit() or via return from the program’s main(). Functions so registered are called in the reverse order of
今天收到RSS订阅中有一篇<Javascript – Arraylike的7种实现>,看第一种实现方式是,瞬间被!function(){}()这种匿名函数自执行方式给亮瞎了眼睛.这种写法绝对是装逼神器,代码如下: !function () { //通过闭包实现 var List = function () { var list = [], self = { constructor: List, //如果希望更像原生一点,将length定义为属性,那么length则需要自己维护 length:
今天脑袋短路,对于这个问题纠结了好久.这个问题具体是这样的: public class test { public static void main(String[] args) { test2 t = new test2(); System.out.println("" + t.i); t.meth(); } } public class test2 { public Integer i=5; test2(){ System.out.println("构造函数")
