Question
Hello, need some help with this Java Assignment--need to create a static method. This assignment has 3 parts and a sample output is provided in the image.
Thank you!
![• Create a new Eclipse project named so as to include your name (eg smith19 or jones19).
• In this project, create a new package with the same name as the project.
• In this package, write solutions to the exercises noted below.
• When done, locate your project in your project workspace and zip it.
• Upload the zip (no rars) to this drop box.
• Submit.
The three exercises below are to be individual methods in a single class file, call each method from the main
Part 1
Write a static method that takes an array of a generic type as its only argument. The method should display the array
and return the number of elements in the array. Test the method in main with at least three arrays of objects.
SAMPLE OUTPUT
Here is an Integer array
12 21 7 16 8 13
That array held 6 elements
Here is a String array
one two three four
That array held 4 elements
Here is a Double array
1.1 2.2 3.3 4.4 5.5
That array held 5 elements
Part 2
public static double listAdder(ArrayList<? extends Number> list) {
???
}
Examine the listAdder method fragment above. Complete the method so that it displays the list elements all on one
line and returns the sum of the elements. Demonstrate the method by calling it in main with ArrayLists of three
different classes that extend class Number. The operator instanceof can test for object type which would be
necessary to have in a foreach loop for the data types types supported (Integer, Byte and Double)
SAMPLE OUTPUT
12 21 7 16 8 13
Integer list totals 77.0
1.1 2.2 3.3 4.4 5.5 6.6
Double list totals 23.1
12 20 4 7
Byte list totals 43.0
Part 3
Implement the following method that returns the maximum element in an array:
public static <E extends Comparable<E>> E max(E[] list)
Write a test program that generates 10 random integers, invokes this method to find the max, and
then displays the random integers sorted smallest to largest and then prints the value returned from
the method.
Max sure the the last sorted and returned value as the same!](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa8d3ff56-1af2-434e-8740-80c67d4b592b%2F40175348-13f1-4826-93d5-ba58030c7aa7%2Fmi4xm8_processed.png&w=3840&q=75)
