Design and implement a spell-checker application in Java. Your program should maintain an
array wordList of strings. Enable the user to enter these strings. [using
file processing. Once you have this capability, you can obtain the words for the spell checker
from a computerized dictionary stored in a file.]
Your program should ask a user to enter a word. The program should then look up that word in
the wordList array. If the word is present in the array, your program should print “Word is
spelled correctly.”
If the word is not present in the array, your program should print “word is not spelled
correctly.” Then your program should try to locate other words in wordList that might be the
word the user intended to type. For example, you can try all possible single transpositions of adjacent
letters to discover that the word “default” is a direct match to a word in wordList. Of course,
this implies that your program will check all other single transpositions, such as “edfault,” “dfeault,”
“deafult,” “defalut,” and “defautl.” When you find a new word that matches one in wordList,
print that word in a message, such as “Did you mean "default?".”
Implement other tests, such as replacing each double letter with a single letter and any other
tests you can develop to improve the value of your spell-checker.

@Poster
Why should u copy the question verbatin here , tell us what u have done so far and which area are u having the problem? I am guessing you must have started something before posting help here

What u need to solve this problem is a Regex(regular expressions) parser. U can call 08034209301 for a solution

@poster
its a nice hint mr femu gave you , search google and read about the use of the java.util.regex package , read on how to use / implement the use of classes in its package , its good algorithm to solve your problem !
do it yourself and post questions here if u have any more questions
