Java Question

[Shadow Ozera]

Hello all, lately iv been learning scanners all over again because iv sorta forgotten what i leaned over the school year. All i'm trying to do is get the tokens from my txt file be displayed. When i compile it, it says it worked but, it doesnt write anything out. I'v saved the txt file in the same folder thats in "My Documents"...did i save it to the wrong place?
Here's my code

Code: Select all

import java.io.*;
import java.util.*;

public class hope{
   
   public static void main(String[] args) throws IOException{
      
      Scanner sc = null;
      
      try{
          sc = new Scanner(new BufferedReader(new FileReader("cat.txt")));
         
         while (sc.hasNext()) {
            System.out.println(sc.next());
            
         }
         
         
      }finally {
      if (sc !=null){
         sc.close();
      }
      
   }
   }      
      
}

For that code to work cat.txt has to be in the same folder as hope.java, which likely isn't the My Documents folder.

Well, i went to my documents, JCreater LE, projects, hope and then i just made a txt file in the hope folder.

Do i have to save it in the src section?

You could try that, that might work. Alternatively, you can use the absolute path to the file, i.e:

Code: Select all

new FileReader("C:\\Documents and Settings\\My Documents\\JCreater LE\\projects\\hop\\cat.txt")

or whatever the path would be.

How would i use that one?

On a completely semi off-topic note.. I really need to start learning JAVA. I just hate how kludgy and bulky the SDK and eclipse are.. everytime I go back to start trying my hand at JAVA the whole concept just pisses me off lolz

What?

You're just specifying where the file, in the case cat.txt is. You can do so using a relative path, meaning a path relative to the folder that you are in. This is what you've attempted in your OP - you're telling your program to look for cat.txt in the same folder that the program itself is in. If you're not sure where cat.txt is relative to the program you can use an absolute path, which is the path irregardless of the folder. For example, say that you are on the page www.site.com/folder/subfolder/page.php and you want to get to anotherPage.php, which is in subfolder. You can use the relative path, which would be ./anotherPage.php, or you can use the absolute path, which would be www.site.com/folder/subfolder/anotherPage.php The . character means current folder, .. means move up one folder. If you want to make things very simple just put cat.txt in you C: drive and then use the path C:\\cat.txt

huh, well i replaced cat.txt with C:\\cat.txt..still nothing. I think il just move on to my next Java project -_-
