Try this code:
public static void initializeArrays(String a[], double b[][]){
try
{
String output = "";
File inputFile = new File("c:/temp/salesdata.txt");
int counter = 0;
if (inputFile.exists())
{
Scanner scanner = new Scanner(inputFile);
while (scanner.hasNext())
{
for (i=1;i<6;i++)
{
b[counter][i]=scanner.nextDouble();
}
counter++;
rowCount += 1;
}
}
}
catch (FileNotFoundException e)
{
System.out.println("Error reading file: ");
