首先,我们需要创建一个txt文件,并通过输出流将文字内容写入文件中。在Java中,可以使用File类和FileOutputStream类来实现。 importjava.io.File;importjava.io.FileOutputStream;importjava.io.IOException;publicclassTextToFile{publicstaticvoidmain(String[]args){// 创建文件对象Filefile=newFile("output.txt");try...
File file = new File(fileentity.getStoreaddress(), uuid); if(file.exists()) { FileInputStream fis; try { fis = new FileInputStream(file); response.setContentType("application/x-msdownload"); response.addHeader("Content-Disposition", "attachment; filename=" + filename ); ServletOutputStre...

PrintWriter out = new PrintWriter("filename.txt"); Then, write your String to it, just like you would to any output stream: out.println(text); You'll need exception handling, as ever. Be sure to close the output stream when you've finished writing. out.close() If you are using...
