Using the string methods that we have learned so far, write a program that will allow the user to type in line of text until the user types in the phrase "The end" on a line by itself. The program will print the number of lines that contain the string "is". Strings have two basic methods that you will need for this assignment:
s.indexOf(t) - which returns the position
where substring t appears in
s. If t does not
appear in s, it returns -1.keyb.nextLine() - which reads in an entire
line of text as a string.
