数组的反转

public class day1 {
    public static void main(String[] args) {
        int[] arr = {12, 54, 98, 74};
        for (int min = 0, max = arr.length - 1;min< max; min++, max--){
            int temp = arr[min];
            arr[min] = arr[max];
            arr[max] = temp;
        }
        for (int i = 0; i < arr.length; i++) {
            System.out.println(arr[i]);
        }
