Reverse Array in Java

It is possible to reverse the order of elements in an array by iterating through the array in a loop starting from the end. The specific code is as follows:

public class Main {
    public static void main(String[] args) {
        int[] arr = {1, 2, 3, 4, 5};
        
        // 逆序输出数组元素
        for (int i = arr.length - 1; i >= 0; i--) {
            System.out.print(arr[i] + " ");
        }
    }
}

In the example above, we start by defining an integer array ‘arr’, then we use a for loop to iterate through the array elements starting from the end, and output each element one by one, achieving the operation of reversing the array.
