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.

This is the code I have, but errors are poping up:

String s;
s = scan.next();
if (s.length() == 12) {
if (first12(s) && last(s.substring(10)) && middle(s.substring(8,10))) {
System.out.print("Yes, ");
System.out.print(s);
System.out.println("matches the pattern");
}
else{
System.out.print("No, ");
System.out.print(s);
System.out.println(" doen't matches the pattern");
}
}
else if(s.length()==14){
if(first12(s) && last(s.substring(11)) && middle(s.substring(8,11))){
System.out.print("Yes, ");
System.out.print(s);

}
else{
