filewriter

问题 I have an application where I am to write values into a file and read them back into the program in a while loop. This fails because the file is only written when I exit the loop and not in every iteration. Therefore, in the next iterations, I cannot access values that were supposed to be written into the file in the previous iterations. How can I make every iteration write into the file as opposed to writing all values at the end of the while loop? My application uses Scalafix. It reads in a

问题 I have this code: String[] strings = {"Hi" , "You", "He", "They", "Tetrabenzene", "Caaorine", "Calorine"}; File file = new File("G:\\words.txt"); FileWriter fWriter; BufferedWriter bWriter; try { if((file.exists())) { file.createNewFile(); } fWriter = new FileWriter(file.getAbsoluteFile(), true); bWriter = new BufferedWriter(fWriter); //Convert Result objects to JSON and write to file for(int j = 0; j < strings.length; ++j) { bWriter.write(strings[j]); bWriter.newLine(); System.out.println(

问题 Every time the code is executed I want a new Text File to be created. The Text File should be called Person1. Next time code is executed the Text File should be called Person2. Then again the Text File should be called Person3. etc, etc.... At the moment, I'm able to create a Text File named "Person1" but can't create another Text File named "Person2". private int fileNumber = 1; fileNumber = fileNumber++; public static void main(String[] args) { try { FileWriter fw = new FileWriter("Person"

问题 I am working on Webmethods Integration Server. Inside there is a java service which is in form of a static java method for writing data to a log file (server.log) by using BufferedWriter and FileWriter. The static method code is like this: public static void writeLogFile(String message) throws ServiceException{ try { BufferedWriter bw = new BufferedWriter(new FileWriter("./logs/server.log", true)); bw.write(message); bw.newLine(); bw.close(); } catch (Exception e) { throw new ServiceException

问题 I am training a simple TensorFlow model. The training aspect works fine, but no logs are being written to /tmp/tensorflow_logs and I'm not sure why. Could anyone provide some insight? Thank you # import MNIST from tensorflow.examples.tutorials.mnist import input_data mnist = input_data.read_data_sets("MNIST_data/", one_hot=True) import tensorflow as tf # set parameters learning_rate = 0.01 training_iteration = 30 batch_size = 100 display_step = 2 # TF graph input x = tf.placeholder("float",

问题 I followed this example: chrome.fileSystem.chooseEntry({type:'openDirectory'}, function(entry) { chrome.fileSystem.getWritableEntry(entry, function(entry) { entry.getFile('file1.txt', {create:true}, function(entry) { entry.createWriter(function(writer) { writer.write(new Blob(['Lorem'], {type: 'text/plain'})); }); }); entry.getFile('file2.txt', {create:true}, function(entry) { entry.createWriter(function(writer) { writer.write(new Blob(['Ipsum'], {type: 'text/plain'})); }); }); }); }); to

问题 Through my Android program I wrote a file like this: String file = Environment.getExternalStorageDirectory().getAbsolutePath() + "/Files/hello.txt"; BufferedWriter writer = new BufferedWriter(new FileWriter(file)); writer.write(str+"\n"); \\yeah string has a value there writer.close(); Now when I go to Android's "Astro" File browser, I can see the file hello.txt in /mnt/sdcard/Files but when I mount the sdcard in Windows, I can only see 4 other files which were there in that folder but not

问题 first time posting in stack - always found previous questions capable enough of solving my prob! Main problem I have is the logic... even a pseudo code answer would be great. I'm using python to read in data from each line of a text file, in the format: This is a tweet captured from the twitter api #hashtag http://url.com/site Using nltk, I can tokenize by line then can use reader.sents() to iterate through etc: reader = TaggedCorpusReader(filecorpus, r'.*\.txt', sent_tokenizer=Line_Tokenizer

问题 I am trying to write to a new file named "filename.txt" and write out "hi" when I open an app. How do I go about this? I run this code in Eclipse, press F11, open up the AVD, and click on the app. I get the "Hello World, appname!" message, but no file is created. package com.paad.comparison; import java.io.BufferedWriter; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.FileWriter; import java.io.IOException; import java.io.InputStreamReader

问题 I admittedly am still learning and would consider myself a novice (at best) regarding programming. I am having trouble with appending a file in android. Whenever I save, it will rewrite over the file, and I am having trouble understanding how to keep the file that is already there and only add a new line. Hoping for some clarity/advice. Here is how I am saving to the file (which rewrites the file each time I save). public void saveText(View view){ try { //open file for writing
