以下是一个完整的 Java 类示例,它使用Files和Paths类从 TXT 文件中读取内容: importjava.nio.file.Files;importjava.nio.file.Paths;importjava.io.IOException;publicclassFileReadExample{publicstaticvoidmain(String[]args){StringfilePath="sample.txt";// 指定文件路径try{Stringcontent=readFileToString(filePath)...
例如,我们创建一个名为“sample.txt”的文件,其内容如下: Hello, this is a sample text file. We will use Java code to read this file. 1. 2. 读取txt文件并存储到String中的Java代码示例 下面是一个简单的Java程序,用于读取名为“sample.txt”的文件并将其内容存储到一个String对象中: importjava.io....
Path path=Paths.get(fileName);//read file to byte arraybyte[] bytes =Files.readAllBytes(path); System.out.println("Read text file using Files class");//read file to String list@SuppressWarnings("unused") List<String> allLines =Files.readAllLines(path, StandardCharsets.UTF_8); System.out...
import java.io.File; import java.io.FileInputStream; import java.io.IOException; import java.util...
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.
Rarely in my career have I written significant amounts of Java, so when Idouse it I’m always learning new things. I thought this unique way to use Scanner to read a text file into a string was great: import java.util.Scanner; String contents = new Scanner(new File(fileName)).useDeli...
try (Stream<String> lines = Files.lines(path)) { lines.forEachOrdered(System.out::println); } } The contents of thethermopylae.txtfile are read and printed to the console using theFiles.linesmethod. Read text file with Scanner AScanneris simple text scanner which can parse primitive types...
