在Java中使用CSV文件的最佳方式

import com.opencsv.CSVReader;
import java.io.FileReader;
import java.io.IOException;

public class ReadCSV {
    public static void main(String[] args) {
        String csvFile = "path/to/your/file.csv";
        try (CSVReader reader = new CSVReader(new FileReader(csvFile))) {
            String[] line;
            while ((line = reader.readNext()) != null) {
                System.out.println("Column 1: " + line[0] + ", Column 2: " + line[1]);
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

import com.opencsv.CSVWriter;
import java.io.FileWriter;
import java.io.IOException;

public class WriteCSV {
    public static void main(String[] args) {
        String csvFile = "path/to/your/output.csv";
        try (CSVWriter writer = new CSVWriter(new FileWriter(csvFile))) {
            String[] header = {"Name", "Age"};
            writer.writeNext(header);
            String[] data1 = {"Alice", "30"};
            String[] data2 = {"Bob", "25"};
            writer.writeNext(data1);
            writer.writeNext(data2);
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
