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 replace every occurrence of "is" with the string "was" and count the number of changes made. 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.s.concat(t) - which returns a string
consisting of the strings s and
t concatenated (or joined) together.s.substring(i, j) - which returns a substring
of s beginning at character
i and ending at character
j-1.s.substring(i) - which returns a substring
of s beginning at character
i and ending at the end of
s.
