创建一个数组并将其转换为List-
Integer[] arr = { 10, 15, 20, 10, 10, 10, 20, 30, 35, 40, 40}; List<Integer> l = Arrays.asList(arr);
现在,让我们将上面的数组转换为HashSet-
Set<Integer> s = new HashSet<Integer>(l);
以下是将数组转换为HashSet的示例-
import java.util.*; public class Demo { public static void main(String[] argv) throws Exception { Integer[] arr = { 10, 15, 20, 10, 10, 10, 20, 30, 35, 40, 40}; List<Integer> l = Arrays.asList(arr); Set<Integer> s = new HashSet<Integer>(l); for (Iterator i = s.iterator(); i.hasNext();) { Object ele = i.next(); System.out.println(ele); } } }
输出结果
35 20 40 10 30 15
