如何将包含字符串和整数的文件读入ArrayList并按整数排序？

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;

public class FileSortExample {
    public static void main(String[] args) {
        String filePath = "path/to/your/file.txt"; // 替换为你的文件路径
        List<Integer> numbers = new ArrayList<>();

        try (BufferedReader br = new BufferedReader(new FileReader(filePath))) {
            String line;
            while ((line = br.readLine()) != null) {
                String[] parts = line.split("\\s+"); // 假设数据以空格分隔
                for (String part : parts) {
                    try {
                        int number = Integer.parseInt(part);
                        numbers.add(number);
                    } catch (NumberFormatException e) {
                        // 忽略非整数部分
                    }
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 对整数进行排序
        Collections.sort(numbers);

        // 输出排序后的结果
        for (int number : numbers) {
            System.out.println(number);
        }
    }
}
