我需要一个Java扫描仪‘重置’无效的字符修复

import java.util.Scanner;

public class ScannerExample {
    public static void main(String[] args) {
        String text = "This is an in无效valid text.";
        
        // 创建扫描仪对象
        Scanner scanner = new Scanner(text);
        
        // 设置扫描仪的分隔符为非字母字符
        scanner.useDelimiter("\\W");
        
        // 读取并打印每个单词
        while (scanner.hasNext()) {
            String word = scanner.next();
            System.out.println("Word: " + word);
        }
        
        // 修复无效的字符
        scanner.reset();
        
        // 重新读取并打印每个单词
        while (scanner.hasNext()) {
            String word = scanner.next();
            System.out.println("Fixed Word: " + word);
        }
        
        // 关闭扫描仪
        scanner.close();
    }
}
