如何删除标点符号，但在Java中保留首字母缩写和连字符单词？

import java.util.regex.Matcher;
import java.util.regex.Pattern;

public class PunctuationRemoval {
    public static void main(String[] args) {
        String sentence = "Hello, World! This is an example sentence. It includes some abbreviations like U.S.A. and hyphenated-words.";
        
        // 删除标点符号，保留首字母缩写和连字符单词
        String result = removePunctuation(sentence);
        
        System.out.println(result);
    }
    
    public static String removePunctuation(String sentence) {
        // 匹配标点符号的正则表达式
        String regex = "[^\\w\\s.-]|(?<!\\w)-(?!\\w)";
        
        // 创建 Pattern 对象
        Pattern pattern = Pattern.compile(regex);
        
        // 创建 Matcher 对象
        Matcher matcher = pattern.matcher(sentence);
        
        // 使用空字符串替换标点符号
        String result = matcher.replaceAll("");
        
        return result;
    }
}

Hello World This is an example sentence It includes some abbreviations like USA and hyphenated-words
