Question
Recognizing strings based on a set of restrictions is a common computational problem. A Slop is a string of characters that has certain properties. Your program will read in strings of characters and output whether or not they are Slops. A Slip is a character string that has the following properties: Its first character is either a 'D' or an 'E' The first character is followed by a string of one or more 'F's The string of one or more 'F's is followed by either a Slip or a 'G' The Slip or 'G' that follows the F's ends the Slip. For example, DFFEFFFG is a Slip since it has a 'D' for its first character, followed by a string of two F's, and ended by the Slip 'EFFFG' Nothing else is a Slip A Slap is a character string that has the following properties: Its first character is an 'A' If it is a two-character Slap then its second and last character is an 'H' If it is not a two-character Slap, then it is in one of these two forms: 'A' followed by 'B' followed by a Slap, followed by a 'C'…

Hawaiian Words CSC220 Must use Java Programming. Write a program that gives the pronunciation of a Hawaiian word. For instance, humuhumunukunukuapua’a phonetic guide would be Hoo-moo-hoo-moo-noo-koo-noo-koo-ah-poo-ah'ah The program should start by prompting for and reading in a Hawaiian word (or phrase) from the user. Check if the word is a valid by checking that it only has valid Hawaiian characters. If the word is not valid, warn the user about the offending character and prompt for a Hawaiian word again. Spaces are breaks for words and should be kept intact. The apostrophe is a hard stop andshould be kept in the word. Print the pronunciation of the word (or phrase). Print a dash after every sound as you see in the examples, so you get the syllables separated. Ask the user if they want to do another word. Valid responses are y, Y, n or N. If they want to play more, they can enter another word. If not, then the program ends. You won’t be able to just use the .replace() method.…
