Method Detail

printMatchingLines

public static void printMatchingLines(java.lang.String searchWord,
                                      java.lang.String corpus)

Find word in multi-line string and print matching lines and line numbers.

For example, given the string:

 Hello, there!
 I'm here.
 You're there.
 Therefore, we're near.
 

If the search term is "there" or "There" or "THERE", the following lines should be printed:

 1: Hello, there!
 3: You're there.
 

If the search term is "I'm" or "i'm", the following lines should be printed

 "2: I'm here."
 

Here are some things to keep in mind:

1. Note that the line numbering is 1-indexed: i.e., the first line is line 1, not line 0, which might be a bit more natural to a computer scientist.
2. Matches are always case-insensitive.
3. The follow characters are considered word boundaries and will never be part of the search term: ' ', '.', '!', '?', ',', ';', '(', ')', '-'
4. So, for example, searching for "two" should match "two fold", "two.", "two!", "two?", "two,", "two;", "(one two)", "(two one)", and "two-fold".
5. You should print to the console in the usual way, not return a string.

Also note the leading space after the line number and colon:

 (number):  (line contents)
 

Your solution must match the expected output exactly, otherwise you will not receive credit.
