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java I/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 a...

Try using Files from java-8 read all the lines from file, and filter lines startsWith 001. Then split string get the values from index 1 try (Stream<String> stream = Files.lines(Paths.get(searchObject + ".txt"))) { List<String> abc = stream.filter(str->str.startsWith("001")...
Scanner inFile =newScanner(fr);// Read lines from the file till end of filewhile(inFile.hasNext()) {// Read the next line.String line = inFile.nextLine();// Display the line.System.out.println(line); }// Close the file.inFile.close(); ...
import java.nio.file.Paths; import java.util.stream.Stream; public class TestReadFile { public static void main(String args[]) { String fileName = "c://lines.txt"; //read file into stream, try-with-resources try (Stream<String> stream = Files.lines(Paths.get(fileName))) { ...
Another option to read text files is to use the Java streaming API. TheFiles.linesreads all lines from a file as a stream. The bytes from the file are decoded into characters using theStandardCharsets.UTF-8charset. Main.java import java.io.IOException; ...

If the file size is small, we can use theFiles.readAllLines()method that reads all lines from a file into aList. By default, bytes from the file are decoded into characters using theUTF-8charset. Note thatFiles.readAllLinesdoes not require explicit resource closing after we have read the ...
// 使用Java.nio读取文本文件List<String>lines=Files.readAllLines(Paths.get("textfile.txt"),StandardCharsets.UTF_8);for(Stringline:lines){System.out.println(line);} 1. 2. 3. 4. 5. 示例代码 下面是一个完整的示例代码,演示如何使用字符流读取文本文件并避免中文乱码问题。
