bufferedreader

I am using a BufferedReader to read details from a file which are stored as bytes, I am then converting the bytes into text and splitting it into an array . However my program is returning a NumberFormatException from the text read from the file. Below I have provided my code, the error message, the line read from the file and the print statement used to show what the BufferedReader has read from the file. FileReader fileReader = new FileReader("VirtualATM.txt"); BufferedReader bufferedReader = new BufferedReader(fileReader); line = bufferedReader.readLine(); System.out.println(line); String

Python 3. I'm using QT's file dialog widget to save PDFs downloaded from the internet. I've been reading the file using 'open', and attempting to write it using the file dialog widget. However, I've been running into a"TypeError: '_io.BufferedReader' does not support the buffer interface" error. Example code: with open('file_to_read.pdf', 'rb') as f1: with open('file_to_save.pdf', 'wb') as f2: f2.write(f1) This logic works properly with text files when not using the 'b' designator, or when reading a file from the web, like with urllib or requests. These are of the 'bytes' type, which I think I

in one line from the standard input I have 3 types of integers: the first integer is id, the second integer is N - some number, and after that follows N integers, separeted by a single space which I want to store in array or ArrayList. How can I do this using BufferedReader? I have the following code: BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String[] line = br.readLine().split(" "); int ID = Integer.parseInt(line[0]); int N = Integer.parseInt(line[1]); My question is is there any elegant way to read the rest of the line and to store it into array? Use Scanner

I'm trying to read a text file, i'm using fileImputStream, and reading all the lines into a single String then outputing it into the console (System.out) When I try to read the humanSerf.txt, it gives me this in the consol: {\rtf1\ansi\ansicpg1252\cocoartf1038\cocoasubrtf360 {\fonttbl\f0\fswiss\fcharset0 Helvetica;} {\colortbl;\red255\green255\blue255;} \paperw11900\paperh16840\margl1440\margr1440\vieww9000\viewh8400\viewkind0 \pard\tx566\tx1133\tx1700\tx2267\tx2834\tx3401\tx3968\tx4535\tx5102\tx5669\tx6236\tx6803\ql\qnatural\pardirnatural \f0\fs24 \cf0 symbol=HS\ strength=15\ agility=13\

here's a code about depth first search in graphs. who knows why bufferedReader class were used in this code? and why nextInt function not used instead? what is its privilege? is it for speeding up processing? Thanks :) import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; class Graph { int g[][]; int v,e; int visited[]; void createGraph()throws IOException { int a,b; BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); System.out.print("\n Enter Number Of Vertices = "); v=Integer.parseInt(br.readLine()); System.out.print("\n Enter

In a JSP project I am reading a file from directory. If i give the full path then i can easily read the file BufferedReader br = new BufferedReader(new FileReader("C:\\ProjectFolderName\\files\\BB.key")); but i don't want to write the full path instead i just want to give the folder name which contains the file, like bellow. BufferedReader br = new BufferedReader(new FileReader("\\files\\BB.key")); How to do this? String currentDirectory = new File("").getAbsolutePath(); System.out.println(currentDirectory); BufferedReader br = new BufferedReader(new FileReader(currentDirectory + "\\files\\BB

I am scraping a few websites and some of them contain non-Latin Characters and special characters like “ for quotes rather than " and ’ for apostrophes rather than ' . Here's the real curve ball... I have the relevant text printed out to the console. Everything encodes fine when I run it in my IDE (Netbeans). But when I run it on my computer “I Need Your Help” is printed out as: ΓÇ£I Need Your HelpΓÇ¥ ... Before anyone says I need to set my JAVA_TOOL_OPTIONS Environment Variable to -Dfile.encoding=UTF8 let me say that I have already done that and this is still a problem. Besides, shouldn't my
