10. 获取一行字符串，按空格切割存到数组中，将数组中的每个数转换为整形，存到集合，然后输出。
public static void main(String args[]) {
int[] a = new int[10];
int i = 0;
ArrayList ns = new ArrayList<>();
ArrayList array1 = new ArrayList();
String line = null;
Scanner reader = new Scanner(System.in);
line = reader.nextLine();
String[] array = line.split(“\\s+”);
for (int j = 0; j < array.length; j++) {
ns.add(Integer.valueOf(array[j]));
array1.add(array[j]);
}
System.out.println(array1);
System.out.println(ns);
}
