如何从x文档中获取数据并将其上传到名为'name‘的新文档中，然后在java中删除旧文档

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.FileReader;
import java.io.FileWriter;
import java.io.IOException;

public class DocumentHandler {
    public static void main(String[] args) {
        String oldDocumentPath = "path/to/old/document.txt";
        String newDocumentPath = "path/to/new/name.txt";

        // 读取旧文档中的数据
        StringBuilder data = new StringBuilder();
        try (BufferedReader reader = new BufferedReader(new FileReader(oldDocumentPath))) {
            String line;
            while ((line = reader.readLine()) != null) {
                data.append(line).append("\n");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 创建新文档并写入数据
        try (BufferedWriter writer = new BufferedWriter(new FileWriter(newDocumentPath))) {
            writer.write(data.toString());
        } catch (IOException e) {
            e.printStackTrace();
        }

        // 删除旧文档
        File oldDocument = new File(oldDocumentPath);
        if (oldDocument.delete()) {
            System.out.println("旧文档删除成功");
        } else {
            System.out.println("旧文档删除失败");
        }
    }
}
