BufferReaders

Posted: Nov 7, 2002 6:35 PM

Ok so I am getting a cannot resolve symbol error pointing to new FileReader, what is wrong? I was wondering why I do not have to give it a path in order to find the file. How does it know where the file is? cause all I am giving it is "foo.txt"...a name. Also, this method needs to write each line of a text file to a vector spot. Any suggestions???

import java.io.BufferedReader;
import java.util.Vector;

public class fileRead{
	
	public static Vector fileVector;
	public static String filename_t="";
	BufferedReader br;
	
	void mrT(String filename){
		
	    this.filename_t=filename;
	    br=new BufferedReader(new FileReader(filename) );
	}
};

hi,

u had not imported the FileReader class.
import java.io.FileReader;

use this statement then u program works fine.
when u give u simply foo.txt then it looks for the current directory. If the .txt file is located other than current directroy u have to give to give full path or create a file object with the full path info.

if any quries let me know.

regards

You can get the current directory with this:

System.getProperty( "user.dir" );

ok, so when I do this, it just prints out every other line instead of all 4 lines of the txt file, why is that?

while(br.readLine()!=null){
      System.out.println(br.readLine());
}

hi,
use the following code

String str1 = br.readLine();
while(str1 != null)
{
System.out.println("read....."+str1);
str1 = br.readLine();
}
