比较java中两个csv文件的内容。

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

public class CSVComparator {
    public static void main(String[] args) {
        String file1 = "file1.csv";
        String file2 = "file2.csv";

        try {
            BufferedReader reader1 = new BufferedReader(new FileReader(file1));
            BufferedReader reader2 = new BufferedReader(new FileReader(file2));

            String line1, line2;
            int lineNumber = 1;

            while ((line1 = reader1.readLine()) != null && (line2 = reader2.readLine()) != null) {
                // 解析CSV数据
                String[] fields1 = line1.split(",");
                String[] fields2 = line2.split(",");

                // 比较CSV数据
                for (int i = 0; i < fields1.length; i++) {
                    if (!fields1[i].equals(fields2[i])) {
                        System.out.println("Difference found at line " + lineNumber + ", field " + (i + 1));
                    }
                }

                lineNumber++;
            }

            reader1.close();
            reader2.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
