输入n个整数，输出其中最小的k个

实现代码：

public static void main(String[] args) {Scanner scanner = new Scanner(System.in);// 读取n和kint n = scanner.nextInt();int k = scanner.nextInt();// 读取n个整数int[] arr = new int[n];for (int i = 0; i < n; i++) {arr[i] = scanner.nextInt();}// 对数组进行排序Arrays.sort(arr);// 输出前k个最小的数for (int i = 0; i < k; i++) {System.out.print(arr[i]);if (i < k - 1) {System.out.print(" ");}}}
