题目5: 巧妙利用SimpleDateFormat求出: 2008-11-11是星期几?(视频下载) (全部书籍) import java.text.ParseException;import java.text.SimpleDateFormat;import java.util.*;public class Test { public static void main(String[] args) { SimpleDateFormat myFormatter = new S
<script> //本月第一天 function showFirstDay() { var Nowdate=new Date(); var MonthFirstDay=new Date(Nowdate.getYear(),Nowdate.getMonth(),1).getDate(); return MonthFirstDay; } //本月最后一天 function showLastDay() {
第一种方法:直接遍历时,用hashset存放,判断是否存在环 第二种方法:使用快慢指针 public class CycleLinkedList { public static void main(String[] args) { Node head = new Node(1); Node node3 = new Node(3); head.next = node3; head.next.next = new Node(5); head.next.next.next = new Node(7);
var firstDate = new Date(); firstDate.setDate(1); //第一天 var endDate = new Date(firstDate); endDate.setMonth(firstDate.getMonth()+1); endDate.setDate(0);alert("第一天:"+firstDate.format('yyyy-MM-dd 00:00:00')+" 最后一天:"+endDate.format('yyyy-
