java 文件操作

1.按行读取

     File file = new File(“your path”);
        BufferedReader reader = null;
        try {
            //System.out.println("以行为单位读取文件内容,一次读一整行:");
            reader = new BufferedReader(new FileReader(file));
            String tempString = null;
            // 一次读入一行,直到读入null为文件结束
            while ((tempString = reader.readLine()) != null) {
                System.out.println(tempString);
                // your code
                
            }
            
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (reader != null) {
                try {
                    reader.close();
                } catch (IOException e1) {
                }
            }
        }
