本文翻译自How to read a file line by line in Java 有时我们想逐行读取一个文件来处理内容。 一个很好的例子是逐行读取CSV文件,然后将其用逗号(,)分成多列。 在Java中,当您需要逐行读取文件时,有多种选项可供选择。 1.Scanner Scanner类提供了用Java逐行读取文件的最简单方法。 我们可以使用Scanner类打开文...
因为csv本质上是一个文本文件,所以可以使用File中的reader方法读取数据; 读取代码如下: 代码语言:java AI代码解释 publicstaticvoidreadFileByLine(Stringfilepath)throwsException{BufferedReaderreader=newBufferedReader(newFileReader(filepath));Stringline=null;if((line=reader.readLine())!=null){System.out.println...
从上面看出,readLine()是调用了read(char[] cbuf, int off, int len) 来读取数据,后面再根据"/r"或"/n"来进行数据处理。 在JavaI/O书上也说了: public String readLine() throws IOException This method returns a string that contains a line of text from a text file. /r, /n, and /r/n are...
void testReadFile1() throws IOException { //文件内容:Hello World|Hello Zimug String fileName = "D:\\data\\test\\newFile4.txt";try (Scanner sc = new Scanner(new FileReader(fileName))) { while (sc.hasNextLine()) { //按行读取字符串 String line = sc.nextLine();System.out.println...
