Question

Write a static method named matchIndex that accepts as its parameter a Scanner for an input file. Your method should compare the first line of the file (target line) to every other line in the file looking for places where the character at a given 0-based index from the two lines is the same. For example, in the strings "hello" and "belt", the characters at indexes 1 ('e') and 2 ('l') match. Your code should be case-sensitive; for example, "J" does not match "j".
For each pair of lines, your method should print output showing the character indexes that match, separated by spaces in the format shown below. If no characters match, print "none" instead as shown below.
For example, suppose the input file contains the following text. (Line numbers and character indexes are shown around the input and matching characters are shown in bold, but these markings do not appear in the actual file.)

This is the target line for comparison
Those achy down socks
Wheels on the school bus go round
The wipers go swish swish swish
His name is Robert Paulson
So long 'n thanks for all the fish
Humpty Dumpty sat on a wall
And then he also had a great fall

When passed the above file, your method would produce the following output:
target and 2: 0 1 3
target and 3: 1 19 27 29
target and 4: 0 1 5
target and 5: 11 17 18
target and 6: 7 13
target and 7: none
target and 8: 9 10 11
target and 9: none
target and 10: 11 14

Notice that lines are not generally the same length. You may assume that the file contains at least 1 line.
