java 敏感词替换星号

好的，我可以帮你编写一个简单的敏感词过滤器，使用星号代替敏感词。以下是Java代码示例：

public class SensitiveWordFilter {
    private static final String REPLACE_CHAR = "*";

    private Set<String> sensitiveWords;

    public SensitiveWordFilter(Set<String> sensitiveWords) {
        this.sensitiveWords = sensitiveWords;
    }

    public String filter(String text) {
        for (String sensitiveWord : sensitiveWords) {
            String replaceString = getReplaceString(sensitiveWord.length());
            text = text.replaceAll(sensitiveWord, replaceString);
        }
        return text;
    }

    private String getReplaceString(int length) {
        StringBuilder stringBuilder = new StringBuilder();
        for (int i = 0; i < length; i++) {
            stringBuilder.append(REPLACE_CHAR);
        }
        return stringBuilder.toString();
    }
}

这个过滤器接受一个敏感词的Set作为构造函数参数，可以通过调用`filter`方法来过滤文本。过滤器会遍历所有敏感词，并使用`getReplaceString`方法生成相应长度的星号字符串来替换敏感词。
