am having a lot of errors pop up, and I need the pattern to follow the instructions below. Please don't send me the program that is already in Bartleby, it isn't right. Professor instructions: Write a Java program that prompts the user to enter a security code that matches a specific pattern. Your program must approve the user's entry. The pattern consists of these characters in this sequence: A lower case character, two upper case characters, two or three digits, two lower case characters, an upper case character, 2 or 3 lower case characters, 2 digits.
