Working with Files in Java

[Aditya Sriram]

Hi all,

I have been working with java for my latest assignment and I ran into some problems while working with files. I need to access a file, word by word but I also want to know when I moved from one line in the file to the next. I don't want to store the entire line in a String and then access it word by word since the amount of data on a single line may be large. Is there a way for me to access the file word by word and still be able to know when a new Line has occurred?

I am currently using scanner and the delimiter by default looks for white spaces so I am getting the content word by word, but when it finishes reading a line, it just jumps to the next one.

what you can do is read the line by line using hasNextLine(), but then when you grab the line, split it up using split() which gives you a string array of every word. you can use delimeter if you want, but it can be problematic.

Scanner inFile = new Scanner(new File("data.txt"));
String inStr;

while (inFile.hasNextLine())
{
    inStr = inFile.nextLine();
    String[] splittedString = inStr.split();

// now you have a String[] array called splittedString of the current line
}

Regular Expressions make sense if you have a specific patter in text lines.
