如何在java中删除文件中的特定文本？

import java.io.*;

public class FileTextRemover {
    public static void main(String[] args) {
        String filePath = "path/to/file.txt"; // 文件路径
        String searchText = "特定文本"; // 要删除的特定文本

        try {
            File inputFile = new File(filePath);
            File tempFile = new File("path/to/temp.txt"); // 临时文件路径

            BufferedReader reader = new BufferedReader(new FileReader(inputFile));
            BufferedWriter writer = new BufferedWriter(new FileWriter(tempFile));

            String currentLine;
            while ((currentLine = reader.readLine()) != null) {
                // 判断当前行是否包含特定文本
                if (!currentLine.contains(searchText)) {
                    writer.write(currentLine);
                    writer.newLine();
                }
            }

            reader.close();
            writer.close();

            if (inputFile.delete()) {
                tempFile.renameTo(inputFile);
                System.out.println("特定文本删除成功！");
            } else {
                System.out.println("特定文本删除失败！");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
