In this experience you will make the neophyte Java programmer happy by solving, to a limited extent, an age-old problem in programming: mismatched delimiters. As we all know, every left bracket needs a matching right bracket and your program will attempt to check this by prompting the user for a string containing delimiter; for example {123456. When you hit ENTER your should report back that you are missing a right delimiter. In fact, your program will check for three possible delimiters: left or right braces {}, left or right parentheses () or left and right brackets []. The error message that will be returned if there is a mismatch depends on the problem. If the right delimiter is missing you will specify "missing right delimiter"; if the left delimiter is missing you will specify what is missing: {([and where in the string the error occurs. For example, iii} should return the following error: "error} at 4". This would indicate no left delimiter. If there are no problems return nothing; simply prompt for the next string until the use hits ENTER to stop the program. Examples: {[hhhhh} would generate missing right delimiter error. However, something such as}}}}} would generate "error :} at 0", "error :} at 1", error :} at 2 ", "error :} at 3 "and "error :} 4 ".
You must use a stack data structure to help you parse the delimiter.
