Record 2: 14.10.2007; +1 (841) 4444444; +90 (542) 3333333

Begin Owner Log
4 records are added to owner table, 0 ignored, 0 overridden :
Record 1: John Michael Moore; +90 (532) 5555555
Record 2: Dubya Bush; +1 (841) 4444444

Record 4: Abdullah Kaktus; +90 (532) 1111111
End of Owner Log

On 12.10.2007 From: John Michael Moore To: Dubya Bush

my project is that we will take inputs from file and commands too.
input1.dat has transactions and input2.dat has phone number owners.
we will output results in another file query.dat

You first problem is to read this. you might do it with readLine and
regex split, and a little indexOf to filter out junk.

see http://mindprod.com/applet/fileio.html for how to read the lines.
see http://mindprod.com/jgloss/regex.html#SPLIT for how to split the
lines up.
see http://mindprod.com/jgloss/string.html for misc string methods.
