This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
First you'd have to define what you meant by that, exactly: probably you mean that each line of the file should be one element in the Vector, right? You could use java.io.BufferedReader class and its readLine() method in a loop. There's a program called "CopyLines" here which shows how to read the lines of a file.
Note that Vector is an old class and its use is discouraged; new code should use java.util.ArrayList as a replacement.
