Java_基础_数组反转

代码

     public static void main(String[] args) {
        int[] arrays={1,2,3,4,5};
        System.out.println("数组没打印前的顺序是：");
        printArray(arrays);
        System.out.println(" ");
        System.out.println("数组打印后的顺序是：");
        int[] reverse=reverse(arrays);
        printArray(reverse);

    }

    public static  int[] reverse(int[] arrays){
        int[] result=new int[arrays.length];

        //反转数组
        for (int i = 0,j=result.length-1; i < result.length; i++,j--) {
            result[j]=arrays[i];
        }

        return result;
    }

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

    }

结果
