Java acquires random source code snippets

Make a record of some important content in the process of writing content. The following information is about java obtaining random time fragments.

import java.text.parseexception;

import java.text.simpledateformat;import java.util.date;public class getrandomtiem {public static void main（string []args）{simpledateformat format = new simpledateformat（"hh:mm:ss"）;date randomdate=randomdate（"00:00:00","24:59:59"）;string randomdats="shi"+randomdate.gethours（）+"f"+randomdate.getminutes（）+"m"+randomdate.getseconds（）;system.out.println（randomdats）;}private static date randomdate（string begindate,string enddate ）{try {simpledateformat format = new simpledateformat（"hh:mm:ss"）;if（start.gettime（） >= end.gettime（））{return null;}long date = random（start.gettime（），end.gettime（））;return new date（date）;} catch （exception e） {e.printstacktrace（）;}return null;}private static long random（long begin,long end）{if（rtn == begin || rtn == end）{return random（begin,end）;}return rtn;}}
