如何对存储在Arraylist...Using Java中的CSV文件进行筛选

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

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

public ArrayList<String[]> filterData(ArrayList<String[]> data, String filterColumn, String filterValue) {
    ArrayList<String[]> filteredData = new ArrayList<>();
    int columnIndex = -1;
    for (int i = 0; i < data.get(0).length; i++) {
        if (data.get(0)[i].equals(filterColumn)) {
            columnIndex = i;
            break;
        }
    }
    if (columnIndex != -1) {
        for (int i = 1; i < data.size(); i++) {
            if (data.get(i)[columnIndex].equals(filterValue)) {
                filteredData.add(data.get(i));
            }
        }
    }
    return filteredData;
}

String filePath = "path/to/your/csv/file.csv";
ArrayList<String[]> data = readCSV(filePath);
String filterColumn = "column_name";
String filterValue = "filter_value";
ArrayList<String[]> filteredData = filterData(data, filterColumn, filterValue);
