X1240: HashTable for Student ID The student ID at a fictitious university encodes various pieces of information. The ID has the format 8YY-MMM-#### where YY is the year of admission, MMM is a code for the college of application, and #### is the sequential numeric order of processing. For example, a student with ID 822-123-0250 was admitted to the university in '22 into the college 123 and was the 250th admission processed that year. Given a string in this format, convert the string into a new string such as YY#### . Then use that key to store the full ID into a hashmap. Write a method that stores into the admissions hash map all of the recoded IDs. Remember, you add words to a HashMap by calling the put() method admissions.put( <>, <>). This admissions table is stored in a HashMap where the key is the converted student ID, and the value is the full representation for the student ID. So for the example above would result in an entry such as: admissions.put("220250", "822-123-0250") The solution looks like this:

Write JAVA code General Problem Description: It is desired to develop a directory application based on the use of a double-linked list data structure, in which students are kept in order according to their student number. In this context, write the Java codes that will meet the requirements given in detail below. Requirements: Create a class named Student to represent students. In the Student class; student number, name and surname and phone numbers for communication are kept. Student's multiple phones number (multiple mobile phones, home phones, etc.) so phone numbers information will be stored in an “ArrayList”. In the Student class; parameterless, taking all parameters and It is sufficient to have 3 constructor methods, including a copy constructor, get/set methods and toString.
