Tokenizing Strings: The tokenizing of a string denotes a process of dividing a string into its components termed as tokens. The “split” method of “String” class could be used for tokenizing strings. The character that would separate tokens is termed as “delimiter”. The argument that is passed to “split” method denotes a regular expression. A regular expression is used to search for patterns in strings, files and other texts. To prevent leading or trailing whitespace characters in tokens, the string is been trimmed. The “trim” method of “String” class is been used for trimming purposes. Wrapper class: The wrapper class is been provided by Java API for numeric data types. These classes contain methods that perform useful operations. It involves primitive numeric values. The static “toString” method converts to a string from a number. The method that accepts number as its argument. It returns a number’s string representation. The “toBinaryString”, “toHexString”, and “toOctalString” accepts integer as argument. It returns string representation of number converted into binary, hexadecimal and octal. The “MAX_VALUE” and “MIN_VALUE” stores maximum and minimum value for a specific data type. The “Autoboxing” denotes a java process for automatically boxing up a value inside an object. The “Unboxing” denotes a reverse process of boxing; it converts a wrapper class object into a primitive type.

The character that would separate tokens is termed as “delimiter”.

The argument that is passed to “split” method denotes a regular expression.

A regular expression is used to search for patterns in strings, files and other texts.

To prevent leading or trailing whitespace characters in tokens, the string is been trimmed.

The “trim” method of “String” class is been used for trimming purposes.

Wrapper class:

The wrapper class is been provided by Java API for numeric data types.

These classes contain methods that perform useful operations.

It involves primitive numeric values.

Please answer JAVA OOP problem below: Assume you have three data definition classes, Person, Student and Faculty. The Student and Faculty classes extend Person. Given the code snippet below, in Java, complete the method determinePersonTypeCount to print out how many Student and Faculty objects exist within the Person array. You may assume that each object within the Person[] is either referencing a Student or Faculty object. public static void determinePersonTypeCount(Person[] people){ // Place your code here }

Please answer JAVA OOP question below: Consider the following relationship diagram between the Game and VideoGame data defintion classes. Game has a constructor that takes in two parameters, title (String) and cost (double). The VideoGame constructor has an additional parameter, genre (String). In Java, efficiently write the constructors needed within the Game class and VideoGame classes. Hint: Remember to think about the appropriate validation

In a shopping cart, there are various items, which can either belong to the category of household items or electronic items. The following UML diagram illustrates the relationship between items, household items, and electronic items. //Implementation Class public class ShoppingCart{ public static void main(String[] args){ final int MAX_ITEM = 50; Item cart = new Item[MAX_ITEM]; addItem(cart); // populate the item array printItem(cart); } } Considering that all the data definition classes and the implementation class are complete, which of the following Object-Oriented Programming (OOP) concepts do you need to use in the above context? i) Polymorphism ii) Method Overloading iii) Method Overriding iv) Dynamic Binding v) Abstract Class Explain, using course terminology, how you would use any of the above concepts to model the given scenario.
