Java replace() problems

Question

I\'m supposed to input a string, and replace all and, to, you, and for substrings with &, 2,

Answer 1

Replace the first rope = rope.replace(" and "," & "); with rope = rope.replace("and "," & ");

Now it should work. The problem was that the first "and" you were trying to replace was and, not and, which is why that was left and did not get replaced.

Also remove the second last line of simplifier, which is System.out.print(rope);. This is duplicate as you are already printing the result in the calling method.

UPDATE: I see what you are trying to do here. Try this:

For each word that you want to replace, replace it only once. So for and, do:

rope.replace("and", "&");

For to, do:

rope.replace("to", "2");

DO NOT add any space between the words, it is not necessary. Doing replace() once will replace ALL occurrences of that word.
