Do Project 5 of Chap. 1 on Page 56.
Write a program that starts with a line of text and then outputs that line of text with the first occurrence of "hate" changed to "love". For example, a possible sample output might be
The line of text to be changed is:
I hate you.
I have rephrased that line to read:
I love you.
Hint: You may consider use the methods: indexOf(A_String) and substring(Start, End) in your program.
