在上面的示例代码中,readFileToString方法接受文件路径作为参数,并返回文件内容的字符串表示。我们使用BufferedReader逐行读取文件,将每一行添加到StringBuilder中。最后,我们将StringBuilder转换为字符串并返回。 要在main方法中调用readFileToString方法,您需要提供文件的实际路径。请将"path/to/your/file.txt"替换为您要读...

This method ensures that the file is closed when all bytes have been read or an I/O error, or other runtime exception, is thrown. After reading all the bytes, we pass those bytes toStringclass constructor to create a new String. Reading file to byte array PathfilePath=Path.of("c:/tem...

2.Files.lines (Java 8) 如果你是需要按行去处理数据文件的内容,这种方式是我推荐大家去使用的一种方式,代码简洁,使用java 8的Stream流将文件读取与文件处理有机融合。 @Test void testReadFile2() throws IOException { String fileName = "D:\\data\\test\\newFile.txt"; ...
