What is the output of the following Java code? public class array {. public static void main(String args[]) {. int []arr = {1,2,3,4,5}; System.out.println(arr[2]); System.out.println(arr[4])For sorting objects in an array, we need only assume that we can compare two elements to see whether the first is bigger than, smaller than, or To initiate an illegal spam campaign, you have a list of email addresses from various domains (the part of the email address that follows the @ symbol).Which of the following is a part of the Oracle database system?

Thats why I searched the net and found Comparable. But even if it did, the Addresses themselves are not an Array, but part of the Object Building. So how on god's earth is one supposed to solved this?5. Which of the following is not a good technique to follow when reading code written by others? 25. Which of the following sorting algorithms utilizes a "divide and conquer" technique to sort arrays with optimal speed? 10. The instanceof operator allows you to determine the type of an object.

I finally understood the more than a few chances of Comparable from java.util.Collections;

I will be able to order an object, for example "Beer" with attributes float content material, String title and String origin in any order that I would like, combining them how I want.

Now the question: I've the following categories (code supplied final):

Building() Address();

Building can also be one of 3 sorts, for instance Dwelling, House, Bungalow.

Now, activity is "to sort all structures, first via the city (ascending), 2d by means of the boulevard (ascending) after which via the boulevard quantity (ascending).

Normally I'd simply sort the checklist first via town, then via street and then by means of quantity. Of path after the first sort its resolution would get blended up by means of the following sorts.

Thats why I searched the net and found Comparable.

Thing is: It did work with the beer example, however does now not with the address. Cause it's applied as an ArrayList, and as I came upon, it just works for Arrays.

But although it did, the Addresses themselves are not an Array, however part of the Object Building.

So how on god's earth is one meant to solved this? I think I spent more than 8 hours with this cr*p, and the students are meant to remedy similiar issues inside 2 - 3 hours.

Any tips are preferred.

Thanks,

Neo
