text-files

问题 I am trying to make the computer read a text file full of words and add it to an ArrayList. I made it work on a regular Java application, but can't get it to work on Android. Can someone help me out? try { FileInputStream textfl = (FileInputStream) getAssets().open("test.txt"); DataInputStream is = new DataInputStream(textfl); BufferedReader r = new BufferedReader(new InputStreamReader(is)); String strLine; while ((strLine = r.readLine()) != null) { tots.add(strLine); //tots is the array list

问题 I'm trying to figure out how to speed up this operation. Before I import a record from the text file I first need to see if one exists in the database. If it does exist I'm going to perform an update operation on it. If it does not exist I'm going to create a new record. Running the code you see below this operation takes somewhere in the neighborhood of 3 hours. I've tried using ADO's find method and it actually appears to be slower than the filter method. The database is a Visual Foxpro 6

问题 How can I read and write an integer to and from a text file, and is it possible to read or write to multiple lines, i.e., deal with multiple integers? Thanks. 回答1: This is certainly possible; it simply depends on the exact format of the text file. Reading the contents of a text file is easy: // If you want to handle an error, don't pass NULL to the following code, but rather an NSError pointer. NSString *contents = [NSString stringWithContentsOfFile:@"/path/to/file" encoding

问题 What is the easiest way to add a text to the beginning of another text file in Command Line (Windows)? 回答1: echo "my line" > newFile.txt type myOriginalFile.txt >> newFile.txt type newFile.txt > myOriginalFile.txt Untested. Double >> means 'append' 回答2: Another variation on the theme. (echo New Line 1) >file.txt.new type file.txt >>file.txt.new move /y file.txt.new file.txt Advantages over other posted answers: minimal number of steps no temp file left over parentheses prevents unwanted

I can get the program to read in the titles into an array and also print in the format that i want, but my problem is searching the file to find matching titles to print them.. The program just prints

问题 I am trying to copy thousands of image files listed in a text file from multiple folders to one folder. The script I have works if all the file names were different. How do I get it to rename duplicates or rename all of them? Either will work as the name isn't important.
