牛客刷题Java实现---统计一个数字在排序数组中出现的次数。

public class Solution {
	public static void main(String[] args) {
		int[] arr = {2,9,4,7,1,9,33,5,9,10,12};
		int k = 9;
		Solution s = new Solution();
		System.out.println(s.GetNumberOfK(arr, k));
	}
	public int GetNumberOfK(int [] array , int k) {
		int number = 0;
		Arrays.sort(array);
		for(int i=0;i

解题思路：先排序，再比较
