Names.java
Objective: To use String methods and file I/O to solve a problem.
Background:
Every year, millions of babies are born in the U.S.A. One of the most important decisions is the baby’s name.
Some names are more popular than others at different times. In 1900, John and Mary were the most popular boy
and girl names. In 2010, Jacob and Emily were the most popular.
You will be given a file of names and their popularity index for the years 1900 to 2010 in ten year increments.
Your task will be to search through the file and print out a chart of popularity for a selected name.
Assignment:
1) First, write a program to use the Scanner next() method to search the text file names.txt for a specific name.
When you find the given name in the file, you read the following 11 integers into an array. The result should
be printed to the screen on a single line, like below.

In this example, Lisa was the 478th most popular name in 2010. In 1900, Lisa was not popular at all and
earned a 0.
2) Once you have accomplished the task above, you should work with the array to create a chart. The chart
should have column headings indicating the years 1900 through 2010, in increments of 10. You should also
include row headings indicating the popularity index, in increments of 20, from 20 to 1000. The popularity
value for each year should be printed in the appropriate row and column. Keep in mind that if the number is
not printed in the given row/column, then dashes should be printed. You should make use of printf. See the
sample run outputs below.
