使用Java比较两个文件并分别存储有用信息

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

public class FileComparator {
    public static void main(String[] args) {
        String file1Path = "file1.txt";
        String file2Path = "file2.txt";
        String usefulInfo1Path = "useful_info1.txt";
        String usefulInfo2Path = "useful_info2.txt";

        try {
            BufferedReader reader1 = new BufferedReader(new FileReader(file1Path));
            BufferedReader reader2 = new BufferedReader(new FileReader(file2Path));
            BufferedWriter writer1 = new BufferedWriter(new FileWriter(usefulInfo1Path));
            BufferedWriter writer2 = new BufferedWriter(new FileWriter(usefulInfo2Path));

            String line1, line2;
            while ((line1 = reader1.readLine()) != null && (line2 = reader2.readLine()) != null) {
                // 比较文件内容并存储有用信息
                if (line1.equals(line2)) {
                    writer1.write(line1);
                    writer1.newLine();
                } else {
                    writer2.write(line2);
                    writer2.newLine();
                }
            }

            reader1.close();
            reader2.close();
            writer1.close();
            writer2.close();

            System.out.println("文件比较完成并存储有用信息成功！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
