JAVA：

public static void readTextFile(String filePath) {        try {            String encoding = "GBK";            File file = new File(filePath);            if (file.isFile() && file.exists()) { // 判断文件是否存在                InputStreamReader read = new InputStreamReader(                        new FileInputStream(file), encoding);// 考虑到编码格式                BufferedReader bufferedReader = new BufferedReader(read);                String lineTxt = null;                while ((lineTxt = bufferedReader.readLine()) != null) {                    System.out.println(lineTxt);                }                read.close();            } else {                System.out.println("找不到指定的文件");            }        } catch (Exception e) {            System.out.println("读取文件内容出错");            e.printStackTrace();        }    }

Python

def readTextFile(filePath):    try:         with open(filePath) as f:            for line in f:                print(line, end='')    except Exception:        print('没有找到此文件')
