1. 使用Java的File类和Scanner类 Java的File类用于表示文件和目录的路径名,并提供了一些方法来获取文件信息。Scanner类则可以用来读取文件内容。下面是一个示例代码: importjava.io.File;importjava.io.FileNotFoundException;importjava.util.Scanner;publicclassFileReader{publicstaticStringreadFileToString(StringfilePath...
以上代码中,readFileAsString()方法接收文件名作为参数,并返回文件内容的字符串形式。该方法使用了 StringBuilder 类来逐行读取文件内容,并将每行内容添加到 StringBuilder 对象中。最后,通过调用toString()方法将 StringBuilder 对象转换为字符串并返回。 在main()方法中,我们可以通过传递文件名参数来调用readFileAsString...
importjava.io.IOException;importjava.nio.file.Files;importjava.nio.file.Paths;publicclassReadFileToString{publicstaticvoidmain(String[]args){String filePath="c:/temp/data.txt";System.out.println(readAllBytesJava7(filePath));}//Read file content into string with - Files.readAllBytes(Path path)pr...
PathfilePath=Path.of("c:/temp/demo.txt");StringfileContent="";StringBuildercontentBuilder=newStringBuilder();try(BufferedReaderbr=newBufferedReader(newFileReader(filePath))){StringsCurrentLine;while((sCurrentLine=br.readLine())!=null){contentBuilder.append(sCurrentLine).append("\n");}}catch(IOEx...
String[] values = new String[xssfRow.getLastCellNum()]; if (xssfRow == null) {//如果为空进入下一个循环 continue; } for (int cellIndex = 0; cellIndex < xssfRow.getLastCellNum() ; cellIndex++) { Cell xssfCell = xssfRow.getCell(cellIndex);//获取某行某列的值 ...
byte[] buffer =getTxTBytes(fileVO,30); HttpHeaders headers = new HttpHeaders(); //防止中文名乱码 //filename = new String(filename.getBytes(StandardCharsets.UTF_8), StandardCharsets.ISO_8859_1); try { headers.setContentDispositionFormData("attachment", filename=java.net.URLEncoder.encode(...
import java.nio.file.Paths; void main() throws IOException { var fileName = "src/main/resources/thermopylae.txt"; var filePath = Paths.get(fileName); byte[] data = Files.readAllBytes(filePath); var content = new String(data);
out.write(fileContent); out.close(); 4、 // 写源文件 PrintStream print = null; try { print = new PrintStream(file.getPath() + "/" + proxy + ".java", "UTF-8"); } catch (Exception e) { e.printStackTrace(); } String code = sb.append("\n").toString(); ...
