Hiring problem

The term "hire" means "to employ" or "to obtain services for a fee." When you hire someone, you are employing or paying them to perform a certain task for you. A step-by-step method for hiring a new employee is an efficient and successful hiring process in which a business determines its talent needs, recruits from its talent pool, and hires the best-qualified individuals. The hiring problem is a well-known decision-making problem in the analysis of algorithms. The problem is solved by designing an efficient algorithm to choose the best candidate from a list of n candidates.

Complete the Kennel class by implementing the following methods: addDog(Dog dog) findYoungestDog() method, which returns the Dog object with the lowest age in the kennel. Assume that no two dogs have the same age. Given classes: Class LabProgram contains the main method for testing the program. Class Kennel represents a kennel, which contains an array of Dog objects as a dog list. (Type your code in here.) Class Dog represents a dog, which has three fields: name, breed, and age. (Hint: getAge() returns a dog's age.) For testing purposes, different dog values will be used. Ex. For the following dogs: Rex Labrador 3.5 Fido Healer 2.0 Snoopy Beagle 3.2 Benji Spaniel 3.9 the output is: Youngest Dog: Fido (Healer) (Age: 2.0)
Instructions-Java Assignment is to define a class named Address. The Address class will have three private instance variables: an int named street_number a String named street_name and a String named state. Write three constructors for the Address class: an empty constructor (no input parameters) that initializes the three instance variables with default values of your choice, a constructor that takes the street values as input but defaults the state to "Arizona", and a constructor that takes all three pieces of information as input Next create a driver class named Main.java. Put public static void main here and test out your class by creating three instances of Address, one using each of the constructors. You can choose the particular address values that are used. I recommend you make them up and do not use actual addresses. Run your code to make sure it works. Next add the following public methods to the Address class and test them from main as you go: Write getters and…

Java programming - please see attched image for initial instruction before the following below. Write a subclass of VowelSeparator that adds three additional methods and a constructor. The class should be named VowelSeparatorAndCounter. Here are the methods to add: void setString(String s) This method should replace the string stored by the object with s. If the argument is null then the method should throw an IllegalArgumentException. (This is an unchecked exception) int getVowelCount() This method should return the number of vowels in the string.int getNonVowelCount() This method should return the number of characters in the string that are not vowels. Write a static method that accepts an array of VowelSeparatorAndCounter objects and returns the total number of vowels contained in all of them. It should have the following signature: public static int totalVowelCount(VowelSeparatorAndCounter[] a)
