在Java中,我们可以录入数组并且可以使用方法将其翻转并且遍历出: public static void main(String[] args) { int[] arr = new int[5];
Scanner sc = new Scanner(System.in); for (int x = 0; x < arr.length; x++) { System.out.println("请输入第" + (x + 1) + "个数字"); int number = sc.nextInt(); arr[x] = number; }
printArray(arr);
reverse(arr);
printArray(arr); }
public static void printArray(int[] arr) { System.out.print("["); for (int x = 0; x < arr.length; x++) { if (x == arr.length - 1) { System.out.println(arr[x] + "]"); } else { System.out.print(arr[x] + ", "); } } }
public static void reverse(int[] arr) { for (int start = 0, end = arr.length - 1; start < end; start++, end--) { int temp = arr[start]; arr[start] = arr[end]; arr[end] = temp; } } } |
