243. Shortest Word Distance

Given a list of words and two words word1 and word2, return the shortest distance between these two words in the list.

For example,
Assume that words = ["practice", "makes", "perfect", "coding", "makes"].

Given word1 = “coding”, word2 = “practice”, return 3.
Given word1 = "makes", word2 = "coding", return 1.

Note:
You may assume that word1 does not equal to word2, and word1 and word2 are both in the list.

注意，一个单词可能在array中出现多次，取distance最小的那一组

public class Solution {
    public int shortestDistance(String[] words, String word1, String word2) {
        int p1=-1, p2=-1;
        int min = Integer.MAX_VALUE;
