如何在Linux上使用Java编写脚本操作进行数据处理

sudo apt update
sudo apt install openjdk-11-jdk

mkdir DataProcessor
cd DataProcessor

import java.io.*;

public class DataProcess {
    public static void main(String[] args) {
        String inputFile = args[0];
        String outputFile = args[1];
        
        try {
            BufferedReader reader = new BufferedReader(new FileReader(inputFile));
            BufferedWriter writer = new BufferedWriter(new FileWriter(outputFile));
            
            String line;
            while ((line = reader.readLine()) != null) {
                // 在这里进行数据处理操作，例如字符串拼接、数据清洗等
                String processedData = "Processed: " + line;
                
                writer.write(processedData);
                writer.newLine();
            }
            
            reader.close();
            writer.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

javac DataProcess.java
