java -从文本提取中省略特殊字符

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

public class SpecialCharacterRemoval {
    public static void main(String[] args) {
        String text = "Hello, @World! How are you? #Java";
        String pattern = "[^a-zA-Z0-9\\s]"; // 匹配非字母、非数字、非空格的特殊字符

        // 创建Pattern对象
        Pattern regex = Pattern.compile(pattern);

        // 创建Matcher对象
        Matcher matcher = regex.matcher(text);

        // 使用空字符串替换特殊字符
        String result = matcher.replaceAll("");

        System.out.println("原始文本: " + text);
        System.out.println("省略特殊字符后的文本: " + result);
    }
