I am trying to read from this file line by line. I can only print the first line properly and the rest of the lines print at the top. please solve this problem using StringTokenizer to read from this file line by line and display it as it is called by its procCode. So when P321 is called only that one shows in the result.

here is what I am getting for my result when I run my program:

P119:XRays:TakeXRays:320.00
P122:Whitening:TeathWhitening:122.99
P321:Cavity:FillACavity:319.00
P650:TopDentures:AddTopDentures:1950.00
P660:BottomDentures:AddBottomDentures:1950.00
P780:Crown:PutInACrown:795.00
P790:RootCanel:ReplaceBadTooth:1019.00
P888:Polishing:xxxxxxxxxx:299.99
Procedure Code = P114
Procedure Name = CleaningExam
Procedure Discription = TeethCleaning
Procedure Cost = 99.99
Procedure Code =
Procedure Name =
Procedure Discription =
Procedure Cost = 0.0

Thanks

The reason you are not getting the other lines is because while reading the file you are just reading the first line.

You have to write a while read read through EOF and then do strink tokenization and then compare and whatever we want to do.

I had made this change after the statement whihc initializes readder variable.

After making the chnage, the output is now as belo:

Procedure Code = P114

Procedure Name = CleaningExam

Procedure Discription = TeethCleaning

Procedure Cost = 99.99

Procedure Code = P119
