我收到“ java.lang.StringIndexOutOfBoundsException：字符串索引超出范围：-3”

Question

SentiWord method takes String arguments and uses tagger method to tag a word as verb or noun....etc When I run this code I get " java.lang.StringIndexOutOfBoundsException: String index out of range: -3 ". I know there are similar questions like this, but I am unable to apply them to get rid of exception.

public static String SentiWord(String stri) {
       MaxentTagger tagger = new MaxentTagger("taggers/english-left3words-distsim.tagger");
           String sample=stri;
            sample = sample.replaceAll("([^a-zA-Z\\s])", "");
            String[] words = sample.split("\\s+");
           String taggedSample = tagger.tagString(sample);
            String[] taggedWords = taggedSample.split("\\s+");
           double totalScore = 0;
            SWN3 test = new SWN3();
            for (int i=0; i<taggedWords.length;i++) {   
               String tail = taggedWords[i].substring(words[i].length() + 1);
                ....
                ...
                }

What I am trying:

if (words[i].length()>0)   // This line
             tail = taggedWords[i].substring(words[i].length() + 1);

But exception doesnt seem to go.Please help.

显然， words[i]的长度比taggedWords[i]尝试出于调试目的同时打印它们，我敢打赌，这就是您所看到的。
