Java Reading input from a text file that has multiple columns

Question

This is an example of the text that I need to manipulate:

YEAR (space) MONTH (space) NAME (space)

YEAR (sapce) MONTH (space) NAME (space)

YEAR (sapce) MONTH (space) NAME (space) ...

How would one go about creating an array using only the values in one column? e.g the second column (months) or the last column (names)

Reading an entire line and splitting on space gives you an array whose elements make up one row. Use array indices to get the desired pieces of information. — Timbits, Sep 04 '11 at 04:59

Take a look at the java.util.Scanner class, specifically the hasNext and next methods.
