使用Java将CSV文件号导入数组，奇怪的“空格”不能修剪

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

public static String[][] readCSV(String filePath) {
    List<String[]> lines = new ArrayList<>();
    try (BufferedReader br = new BufferedReader(new FileReader(filePath))) {
        String line;
        while ((line = br.readLine()) != null) {
            String[] values = line.split(",");
            lines.add(values);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return lines.toArray(new String[0][]);
}

String[][] data = readCSV("path/to/your/csv/file.csv");

public static String[][] readCSV(String filePath) {
    List<String[]> lines = new ArrayList<>();
    try (BufferedReader br = new BufferedReader(new FileReader(filePath))) {
        String line;
        while ((line = br.readLine()) != null) {
            String[] values = line.split(",");
            for (int i = 0; i < values.length; i++) {
                values[i] = values[i].trim(); // 修剪空格
            }
            lines.add(values);
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return lines.toArray(new String[0][]);
}
