.java文件转换txt

您可以使用以下代码将Java文件转换为txt文件：

import java.io.*;

public class JavaToTxt {

    public static void main(String[] args) {
        String fileName = "file.java";
        String outputFileName = "file.txt";

        try {
            File file = new File(fileName);
            FileReader reader = new FileReader(file);
            BufferedReader br = new BufferedReader(reader);

            FileWriter writer = new FileWriter(outputFileName);
            BufferedWriter bw = new BufferedWriter(writer);

            String line;
            while ((line = br.readLine()) != null) {
                bw.write(line);
                bw.newLine();
            }

            br.close();
            bw.close();

            System.out.println("Java file has been converted to txt file successfully!");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

您需要将`fileName`变量设置为要转换的Java文件的名称，并将`outputFileName`变量设置为要输出的txt文件的名称。然后运行该程序即可。
