replace the "a" in a sentence to "the"

Question

dc · Accepted Answer

this is how i would do it, in pseudocode:

create a StringBuffer to add individual characters and eventually return.
string to char array
iterate through the char array
if a character is 't', check the next chars to see if they are 'h' and 'e' respectively. if so, just add 'a' and jump to the proper index in the array
if character isn't 't', just add to the StringBuffer
return StringBuffer to string

or some kind of while using indexOf('the'), but using a StringBuffer instead of lots of String concatenations

Simply use string::find and string::replace functions.

NO need to use String.find(). just use string.replaceAll("the","a");
