在Java中使用示例的Set toArray()方法Set是Java中一个非常常用的接口之一。它是一个无序且不允许重复元素的集合,根据不同的实现类,可以有不同的底层数据结构来支持不同的操作和执行效率。而Set接口中的toArray()方法,则提供了一种将Set转换为数组的快捷方式。
示例1: // Java code to illustratetoArray()importjava.util.*;publicclassSetDemo{publicstaticvoidmain(String args[]){// Creating an empty SetSet<String> abs_col =newHashSet<String>();// Use add() method to add// elements into the Setabs_col.add("Welcome"); abs_col.add("To"); ab...
下⾯是两个⽅法的申明及说明,摘⾃Java8的API⽂档。toArray()⽅法的分析Object[] toArray()Returns an array containing all of the elements in this list in proper sequence (from first to last element). The returned array will be “safe” in that no references to it are maintained by...
Java TreeSet的toArray()方法用于生成与TreeSet相同的元素的数组。本质上,它将所有元素从TreeSet复制到新数组。 用法: Object[] arr = TreeSet.toArray() 参数:该方法不带任何参数。 返回值:该方法返回一个包含与TreeSet类似的元素的数组。 以下示例程序旨在说明TreeSet.toArray()方法: ...
(array1, 0); object[] array2 = list.ToArray(); string[] array3 = (string[])list.ToArray(typeof(String)); foreach (string s in array1) { Console.WriteLine(s); } foreach (string s in array2) { Console.WriteLine(s); } foreach (string s in array3) { Console.WriteLine(s);...
