	public static void main(String[] args) {
        Scanner input = new Scanner(System.in); // TODO 自动生成方法存根
        String[] names = new String[10];
 
        for (int i = 0; i < 10; i++) {
            System.out.println("请输入第" + (i + 1) + "学生姓名：");
            names[i] = input.nextLine();
 
        }
        for (String s : names) {
            System.out.println(s);
        }
    }
	

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<Integer> ns = new ArrayList<>();
		ArrayList<String> array1 = new ArrayList<String>();
		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);
	}
