题意: 对于给定的采用”yyyy/mm/dd”加24小时制(用短横线”-”连接)来表示日期和时间的字符串, 请编程实现将其转换成”mm/dd/yyyy”加12小时制格式的字符串,末尾加上pm或者am. 思路: 使用java的date与SimpleDateFormat, 注意HH是24小时制,而hh是12小时制, 如果加pm,am,需要添加参数a和Locale.ENGLISH 如:SimpleDateFormat("MM/dd/yyyy-hh:mm:ssa",Locale.ENGLISH…

这里指的java速成,只限于java语法,包括输入输出,运算处理,字符串和高精度的处理,进制之间的转换等,能解决OJ上的一些高精度题目. 1. 输入: 格式为:Scanner cin = new Scanner (new BufferedInputStream(System.in)); 例程: import java.io.*; import java.math.*; import java.util.*; import java.text.*; public class Main { publ…
