Our company is using some software that ONLY accepts input from an "Imaging Device" i.e. a TWAIN device (e.g. scanner). The problem is that we are receiving our files digitally, so using an actual scanner would require us to print, scan, and shred documents that we already have on the computer, but not in the software. I was curious if...
I'm using scanner to read a text file line by line but then how to get line number since scanner iterates through each input?My program is something like this: s = new Scanner(new BufferedReader(new FileReader("input.txt"))); while (s.hasNext()) { System.out.print(s.next()); This works fine but for example: 1,2,3 3,4,5 I want to...
If I have the following example file where each number is represents a byte (123 has bytes 1, 2, and 3): 123456789 Let's say I create a FileInputStream. This reads in the binary byte by byte. So .read() returns 1, then 2, etc. Now let's say I create a buffer. The initial chunk it reads in (if I understand buffers correctly) is 1-5. Th...

Hi, I am trying to do as my question states, sooo I have the following code which would find the match. String test = scan.next(); if (test.equals("$let")) return 1; However, I would prefer to use hasNext as to not consume a token; however, when i do the following it fails. if (scan.hasNext("$let")) return 1; I realize the whe...
I have a .txt file that has numbers 1-31 in it called numbers. I've set up a scanner like this: cardCreator = new Scanner (new File ("numbers")); After this, I'm kind of confused on which methods I could use. I want to set up a conditional statement that will go through numbers, evaluate each line (or numbers 1-31), and includ...
I have a text file which looks like: name1 1 0 1 0 1 0 1 1 1 0 0 0 0 0 0 name2 1 0 1 0 1 0 0 1 1 0 0 0 0 0 1 i.e., a plaintext label followed by a few rows with 1/0 separated by spaces. The number of rows of 1/0 is variable, but each row between any two particular labels should have the same number of 1/0s (though might potentially n...
I'd like to specify a delimiter for a scanner that splits on some pattern, but doesn't remove that pattern from the tokens. I can't seem to make this work, as anything that is identified by the regex also gets eaten as part of the delimiter. Any suggestions? My specific problem, I have file that looks like: text/numbers mix numbers n...
I'm having a trouble using SANE on Python to scan an image on a Kodak scanner. The real headache comes to when I close the scanner device after getting the image, it just disappears from the SANE Devices lists until I restarted the Python interpreter, making impossible to scan another image. It just acts like that with this scanner, I'...

Hi all, I decided to create a currency converter in Java, and have it so that it would pull the conversion values out of a text file (to allow for easy editability since these values are constantly changing). I did manage to do it by using the Scanner class and putting all the values into an ArrayList. Now I'm wondering if there is a w...
