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)...
StringBuffer sb = new StringBuffer(); BufferedReader br = new BufferedReader(new InputStreamReader(getClass().getResourceAsStream("path/to/textfile.txt"), "UTF-8")); for (int c = br.read(); c != -1; c = br.read()) sb.append((char)c); System.out.println(sb.toString()); ...
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...
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...

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...
