数组的四个特点

反转数组：

package array;

public class demo02 {
    public static void main(String[] args) {
int []arrays={1,2,3,4,5};
int []reverse=reverse(arrays);
printArray(reverse);
    }

    public static int[] reverse(int[] arrays) {
        int[] result = new int[arrays.length];
        for (int i = 0, j = arrays.length - 1; i < arrays.length; i++, j--) {
            result[j] = arrays[i];


        }return result;

    }
    public static void printArray(int[] arrays){
        for (int i=0;i<arrays.length;i++){
            System.out.print(arrays[i]+" ");
        }
    }
}
