假设以下是我们的字符串数组 −
String arr[] = { "Andy","John","Kevin","Mary","Ryan" };
现在，使用 HashSet 将数组转换为集合 −
Set<String>set = new HashSet<>(Arrays.asList(arr));
示例
以下是 Java 中将数组转换为集合的程序 −
import java.util.*;
public class Demo {
public static void main(String[] args) {
String arr[] = { "Andy", "John", "Kevin", "Mary", "Ryan" };
System.out.println("Array = "+ Arrays.toString(arr));
Set<String>set = new HashSet<>(Arrays.asList(arr));
System.out.println("Set = " + set);
}
}
输出
Array = [Andy, John, Kevin, Mary, Ryan] Set = [Kevin, Ryan, John, Andy, Mary]
