修改以下代码中的错误并标出 public boolean classify(String text) { String[] words = text.split("\\s+"); double spamScore = 0.0; double hamScore = 0.0; for (String word : words) { if (word.length() < 3) { continue; } word = word.toLowerCase(); if (spamWords.containsKey(word)) { spamScore += Math.log((double) spamWords.get(word) / spamCount); } else { spamScore += Math.log(0.01 / spamCount); } if (hamWords.containsKey(word)) { hamScore += Math.log((double) hamWords.get(word) / hamCount); } else { hamScore += Math.log(0.01 / hamCount); } } return spamScore > hamScore; }

public boolean classify(String text) {
String[] words = text.split("\\s+");
double spamScore = 0.0;
double hamScore = 0.0;
for (String word : words) {
if (word.length() < 3) {
continue;
}
word = word.toLowerCase();
if (spamWords.containsKey(word)) {
spamScore += Math.log((double) spamWords.get(word) / spamCount);
} else {
spamScore += Math.log(0.01 / spamCount);
}
if (hamWords.containsKey(word)) {
hamScore += Math.log((double) hamWords.get(word) / hamCount);
} else {
hamScore += Math.log(0.01 / hamCount);
}
}
return spamScore >= hamScore; // 修改为 >=
}
将最后的 `return spamScore > hamScore;` 改为 `return spamScore >= hamScore;`,因为在 `spamScore == hamScore` 时应该返回 false。
