java.util.SimpleTimeZone.clone() Java.util.ServiceLoader.toString() java.util.SimpleTimeZone.equals() 描述 该clone()方法用于返回此的SimpleTimeZone实例的一个副本。 声明 以下是java.util.SimpleTimeZone.clone()方法的声明。 public Object clone() 参数 NA 返回值 方法调用返回此实例的克隆。 异常 NA 实例 以下示例显示了java.util.SimpleTimeZone.clone()的用法 package com.tutorialspoint; import java.util.*; public class SimpleTimeZoneDemo { public static void main( String args[] ) { // create simple time zone object SimpleTimeZone stobj = new SimpleTimeZone(720,"India"); System.out.println("Origial obj: " + stobj); // clone the object Object cloneObj = stobj.clone(); System.out.println("Clone obj: " + cloneObj); } } 让我们编译并运行上面的程序,这将产生以下结果。 Origial obj: java.util.SimpleTimeZone[id = India,offset = 720,dstSavings = 3600000, useDaylight = false,startYear = 0,startMode = 0,startMonth = 0,startDay = 0, startDayOfWeek = 0,startTime = 0,startTimeMode = 0,endMode = 0,endMonth = 0, endDay = 0,endDayOfWeek = 0,endTime = 0,endTimeMode = 0] Clone obj: java.util.SimpleTimeZone[id = India,offset = 720,dstSavings = 3600000, useDaylight = false,startYear = 0,startMode = 0,startMonth = 0,startDay = 0, startDayOfWeek = 0,startTime = 0,startTimeMode = 0,endMode = 0,endMonth = 0, endDay = 0,endDayOfWeek = 0,endTime = 0,endTimeMode = 0] Java.util.ServiceLoader.toString() java.util.SimpleTimeZone.equals()
