        int[] a = {10,20,30,40,50,60};

        for (int i = 0, j = a.length-1;i < j; i++,j--) {
            int temp = a[j];
            a[j]=a[i];
            a[i]=temp;
        }
        System.out.println("前后元素调换后数组：");
        for (int i = 0; i < a.length; i++) {
            System.out.print(a[i]+"\t");
