What I meant by the psuedocode "Ignore token and go on" was to simply just do nothing with the token. Just add the ones that are ints.

String temp;
// I just fixed it to define temp before the...

Also, you have an empty else.

import java.io.BufferedReader;
import java.io.FileReader;
import java.io.IOException;
import java.util.ArrayList;
import java.util.StringTokenizer;

public class Main {
private static String...

sCurrentLIne = s.readLine();

For starters, what exactly are you trying to add?

Each number individually, each number as a pair, each number as a pair with reference to another pair?

To add it, do something perhaps like...

Well, to separate the numbers and the text and symbols, maybe you could use a StringTokenizer.
StringTokenizer (Java 2 Platform SE v1.4.2)

int n = myArray.size();
for (int i = 0; i < n; i++) {
System.out.println(myArray.get(i));
}

You never added anything.

Your size will be 0.

You have to

// Print line as read from file
System.out.println(sCurrentLine)

Well, to just print out the lines alone read from the file without doing anything to them,

well....you'd need...

mat = pat.matcher(sCurrentLine);

sCurrentLine hasn't been initialized yet.

sCurrentLine = s.readLine()) != null

First off,

sCurrentLine ==s.readLine()

while ((sCurrentLine = s.readLine()) != null) {

This line won't work.
