Need sugestions to solve this annoying problem

Question

Hey everyone, after many hours i decided to ask for your help.
Here's the problem.
I have two txt. files one of them has :
1st txt:
Barcelona 14 20 // Airport , x and y (coord.)
Caliornia 30 40
Paris 2 15
Fiji 20 23
and the 2nd txt file has:
40 // number of flights for exemple
C 0025 Barcelona California // type, number, Start point , destiny
A 0045 California fiji
C 0032 Barcelona Paris
C 0047 Paris Barcelona
A 0078 fiji Paris
C 0065 California Barcelona
So what im trying to do is if the type is "C" (Comercial) catch the coordenates from the start point and the arrived point...to do that i think we must compare (don't know how) those strings with the other strings from the 1st txt file, because the coordenates are inside the first txt. file. I need to catch the coordenates from the start point and from the destiny point, so we can't give a line , beacause it must be a dynamic way , this operation must result to any txt. file (2nd one) it can has 5 flights or 50 flights, just has to
return all the coordenates ( x1 y1 ) and (x2 y2) .
Any sugestion?
What i already did, was to insert all the names into a String [ ] , and then inserted into a LinckedList , so its like: e.g String word [ ] :
word[0] has all the names word [1] has all the xx's , word[2] the yy's this for the 1st txt file.
For the 2nd , i did the same thing but this one has four columns.
another String [ ] ...words [0] has all the types , words[ 2] the start points and words [3] the destiny point.
Need a serious help with this thing.
[[]] thanks everyone!!

Answer 1

loop through file 2 adn check if first word[0] is a C
if it is a C get file2.word[2] and lopp through file1 and check if file2.word[2] is equal to file1.word[0]
if equal save file1.word[1] in a new arrary or something
then get file2.word[3] and lopp through file1 and check if file2.word[3] is equal to file1.word[0]
if equal save file1.word[1] in a new arrary or something
