Printing Sentences From A List?

I'm trying to print sentences from a list which read in sentences from a text file. I'm able to get the program to print out the sentences in a numbered format corresponding to each sentence, but the first sentence in the list is always repeated, same as the next sentence. How can I print out the contents of a list in a numbered format (1. _ 2. _ 3._) without repeating sentences?

Here's my code:

package jacsim; 
import java.util.Scanner;
import java.io.File;
import java.util.Arrays;
import java.util.List;
import java.util.ArrayList;
import java.io.FileInputStream;

[Code] ....

The output looks like:

Input Sentences:
1:The cat in the hat
2:The cat in the hat The cat sat on the mat
3:The cat in the hat The cat sat on the mat Pigs in a blanket

Sorted Single Arrays:

I'm trying to make it look like:
1. The cat in the hat
2. The cat sat on the mat
3. Pigs in a blanket
