数组倒序

//1 、在原数组上进行操作
package test;

public class Test014 {
    public static void main(String[] args) {
        int[] arr = new int[]{35, 5, 22, -98, 6,34, 0};
        for (int i = 0; i < arr.length/2; i++) {
            int temp=arr[i];
            arr[i]=arr[arr.length - 1 - i];
            arr[arr.length - 1 - i] = temp;
        }
        for (int i = 0; i < arr.length; i++) {
            System.out.print(arr[i] + " ");

        }
    }
}
//2、生成一个新的数组，原数组倒序装载到新数组中

package test;

public class Test014 {
    public static void main(String[] args) {
        int[] arr = new int[]{35, 5, 22, -98, 6, 34, 0};
        int[] arrs = new int[arr.length];
        for (int j = 0, i = arr.length - 1; i >= 0; i--, j++) {
            arrs[j] = arr[i];

        }
        for (int i = 0; i < arrs.length; i++) {
            System.out.print(arrs[i] + " ");

        }
    }
}
