- The compareTo method. First you compare this.ticker which is a String, then if they are the same then you compare by the this.purchasePrice which is a double hashCode public int hashCode() The hashCode method using the Code-> Generate equals and hashCode with no changes Overrides: hashCode in class Object Returns: int Representing the hashCode compareTo public int compareTo(Stock another) The compareTo method not auto generated Compares first by ticker and if the tickers are the same secondarily compares by price Specified by: compareTo" in interface Comparable<stock> Parameters: another - the object to be compared. Returns: int Representing order Throws: IllegalArgumentException"- if another is null.for (String name : likedBy) { String likedUser= name.trim(); Set<String> likes = likesMap.getOrDefault(likedUser, new HashSet<>()); Here you create a new Set for likes.

- Bean Scopes Suppose you are working on an application that involves encrypting passwords before storing them in the database. The encryption part is carried out by a PasswordEncryptor class. This class provides you with a method that takes a plaintext password and returns an encrypted one. You need to create a bean of this class. What should be the scope of this bean? Choose the correct option from those given below. (Hint: PasswordEncryptor only contains methods and no fields to maintain state. Hence, we need to create a stateless bean of PasswordEncryptor. Recall which bean scope is used for creating stateless beans.) 1) Prototype 2) Singleton 3) Request 4) SessionProvide right solutionpython: def typehelper(poke_name): """ Question 5 - API Now that you've acquired a new helper, you want to take care of them!
