## Example Code and Explanation### Code Example:```javaObject arg = "Kean";System.out.println(arg);arg = 1234;System.out.println(arg);arg = true;System.out.println(arg);```### Output:```Kean1234true```### Explanation:- The `Object` type can store different data types, demonstrating polymorphism in Java. - This example initializes `arg` with a `String`, then an `int`, and finally a `boolean`, printing each value.---## Method Explanation### Method: RecursiveMethod- Takes two `Object` type arguments.- Returns `True` if both arguments are of the same data type and contain the same value; otherwise, it returns `False`.---## Sample Run### Sample Code:```javapublic static void main(String[] args){ System.out.println(RecursionProblem(12, 12)); System.out.println(RecursionProblem(245, "245")); System.out.println(RecursionProblem(true, false)); System.out.println(RecursionProblem("Kean", "Kean")); System.out.println(RecursionProblem("KEAN", "Kean")); System.out.println(RecursionProblem("K", 'K')); System.out.println(RecursionProblem(340.6, 340.6));}```### Output:```truefalsefalsetruefalsefalsetrue```### Explanation:- The `RecursionProblem` method evaluates the equality and data type of its two arguments. - `RecursionProblem(12, 12)` returns `true` because both are integers with the same value. - `RecursionProblem(245, "245")` returns `false` because they are of different data types (`int` vs. `String`). - `RecursionProblem(true, false)` returns `false` because the boolean values differ. - `RecursionProblem("Kean", "Kean")` returns `true` since both Strings are identical. - `RecursionProblem("KEAN", "Kean")` returns `false` due to case sensitivity. - `RecursionProblem("K", 'K')` returns `false` because one is a `String` and the other is a `char`. - `RecursionProblem(340.6, **Question 2: Implementing a Recursive Function**Implement a method named **"RecursiveProblem"**. This method takes two arguments whose data types are **"Objects"**.Object Data Type is a non-primitive data type, and it can be referenced with any primitive data type i.e. It can be assigned values that belong to either int or float or string or char data types.

Example: Object arg = "Kean"; System.out.println(arg); arg = 1234; System.out.println(arg); arg = true; System.out.println(arg); Output Kean 1234 true The method called as "RecursiveMethod" takes two Object type arguments. This method should return either True or False if the two arguments belong to same data type and also have the same value. Sample Run: public static void main(String[] args) { System.out.println (Recursion Problem (12,12)); System.out.println (Recursion Problem (245, "245")); System.out.println(Recursion Problem (true,false)); System.out.println (RecursionProblem("Kean", "Kean")); System.out.println (Recursion Problem ("KEAN", "Kean")); System.out.println(RecursionProblem("K", 'K')); System.out.println (Recursion Problem (340.6,340.6)); } Output: true false false true false false true

Write a method body of a method: InsertNum(int num) This method will be self intelligent to place the user entered number at desired position of the array. But at runtime it's behaviour will change in case of unsorted array it places the number in array at constant time. i.e. Big0(1) Code the method by keeping above scenario in mind. (Code in C++) don't use pointers

I already have the code for the assignment below, but the code has an error in the driver class. Please help me fix it. The assignment: Make a recursive method for factoring an integer n. First, find a factor f, then recursively factor n / f. This assignment needs a resource class and a driver class. The resource class and the driver class need to be in two separate files. The resource class will contain all of the methods and the driver class only needs to call the methods. The driver class needs to have only 5 lines of code The code of the resource class: import java.util.ArrayList;import java.util.List; public class U10E03R{ // Recursive function to // print factors of a number public static void factors(int n, int i) { // Checking if the number is less than N if (i <= n) { if (n % i == 0) { System.out.print(i + " "); } // Calling the function recursively // for the next number factors(n, i +…
void Date: addDays (int n); void Date: subtractDays(in n); The addDays method will add n number of days to the current date that's stored in Object's data. For example, object hold 4/21/2022 as the date and if user of this object calls addDays (10) method, it will add 10 days to 4/21/2022 giving a new date of 5/1/2022. There can be more complicated scenarios if you add a lot of days (for example hundreds of days) due to possible rollover of year and months. You can limit number of days to be added to 100. Just like addDays, subtractDays method will subtract number of days from the current date. Provide implementation of both functions in the class. Also modify your main function as follows:
