 BufferedReader finput = 
		new BufferedReader(new FileReader("ad.txt")); 

I want this to read a my documents file. How can I do that?

[no2pencil]

Something like the following?

		File in = new File(
				"/Documents and Settings/user/ad.txt");
		BufferedReader reader = new BufferedReader(new FileReader(in));
		String line = "";
		while ((line = reader.readLine()) != null)
		{
			...
		}

@no2pencil, pbl is not gonna like that while line, since you assigned a variable a value in it.

Just warnin' ya.

Use Scanner then you can hasNext()

It's all good. I'm not that great with Java, I pulled some example file reading code.

I'd rather know how to do it correctly.

any way to call it straight through this
BufferedReader finput =
new BufferedReader(new FileReader("ad.txt"));


I dont want any extra coding or anything

If you don't want extra coding use a Scanner

Scanner in = new Scanner(new File("ad.txt"));
while(in.hastNext()) {
   String line = in.nextLine();
}

If i were not to use a scanner then where would i need to place the file? in the same folder as the java class?

long story no2pencil
Locke has good memory

Despite the fact your code is syntaxly correct.. and woul be seen often in C/C++ coding Java avoids to assign a value inside a if/while statement
Locke is refering on an article on Sun site where Sun Engineering thought once at simply forbidding variable assignment inside if/while
so your corrected code (1 more line of code) would be

String line = reader.readLine();				
while ((line  != null)	{
   ...				
   line = reader.readLine();				
} 

At least Locke learned and remember it

Use the full path for the file:

// assuming windows
BufferedReader finput = 
		new BufferedReader(new FileReader("C:\\Documents and Settings\\Owner\\My Documents\\ad.txt"));

I just remember that you don't like that. I do it "no2pencil"'s way, since that was the first few examples that I learned. I could do it your way, but it's more lines. (granted, only by 2)

Question is irrelevant... you will have the same problem if you were using a BufferedReader

Scanner in = new Scanner(new File("ad.txt"));

assumes ad.txt is in the same directory

Scanner in = new Scanner(new File("/data/ad.txt"));

in the subdir data

Scanner in = new Scanner(new File("../../ad.txt"));

2 directories up

Test for null and all the try and catch

If you know how, then you could also use a JFileChooser and yea there are more steps but that is one method to find a file fromt he entire computer not a specific folder
