在Java中将数组转换为HashSet
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-
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
