combining two separate codes into one

So, you say that the while loop will only read the first line...correct ?

No... what I said was the it will loop only once (because the the return statement is at the end of the while statement). It will execute any code in the while loop, but only once.

So I ask again... where should the return statement be moved to?

I made the following change in the code, by taking the return statement outside the while loop.

public static double[] fileread(String fName) throws IOException  
{

String thisLine; //string variable to take each record at a time

int count=0; 
int x=0;



double dblArray[];

FileInputStream fis = new FileInputStream(fName); 
//A FileInputStream obtains input from a file 

DataInputStream myInput = new DataInputStream(fis);
/*data input stream lets an application read primitive Java data types 
from an underlying input stream*/

while ((thisLine = myInput.readLine()) != null)
{ //beginning of outer while loop 

String[] result = thisLine.split(",");
dblArray = new double[result.length];
     for (x=0; x<result.length; x++)
     	
        {    	/*return result[x];*/ 
        	dblArray[x] = Double.parseDouble(result[x]);
        	
        		
         }

} 
 	return dblArray;
}

But, it shows the following error:-

C:\Users\Jaimin\Documents\JCreator Pro\MyProjects\finalcode2.java:69: variable dblArray might not have been initialized
return dblArray;

I have already declared dblArray variable in the beginning of the method. However, an error like above is shown. why ?
