Answer:

See Explanation

Explanation:

The following lines of codes were corrected.

Note only lines with error are listed out

char[] okayCodes = {'A''C''T''H'};

corrected to

char[] okayCodes = {'A','C','T','H'};

StringBuffer prompt = newStringBuffer("Enter shipping code for this delivery\nValid codes are: ");

corrected to

StringBuffer prompt = new StringBuffer("Enter shipping code for this deliveryValid codes are: ");

for(int x = 0; x < length; ++x)

corrected to

for(int x = 0; x < okayCodes.length; ++x)

for(int i = 0; i < length; ++i)

corrected to

for(int i = 0; i < okayCodes.length; ++i)

if(userCode = okayCodes)

corrected to

if(userCode == okayCodes[i])

if(found)message = "Good code";elsemessage = "Sorry code not found";

corrected to

if(found)

message = "Good code";

else

message = "Sorry code not found";

However, I've added the full source code as an attachment
