Why the utility class should be static? Is it just because we can call the utility methods without creating an object or any other reasons also?
@ConceptandCoding 10 ай бұрын
Utility class generally do not change the status of the object. Its method just accept the parameter, do some logic and return the output but it do not change the object status

@sheyansh, could you please provide one sample example on Collections.binarySearch method ?
@ConceptandCoding 5 ай бұрын
public class BinarySearchExample { public static void main(String[] args) { List numbers = new ArrayList(); numbers.add(1); numbers.add(3); numbers.add(8); numbers.add(11); numbers.add(14); int key = 8; // Sorting the list first before performing the binary search Collections.sort(numbers); // Performing binary search now int index = Collections.binarySearch(numbers, key); System.out.println("Element " + key + " not found in the list"); } } In this example, the binarySearch method is used to search for the element 8 in a sorted list of numbers. The list is sorted using Collections.sort before applying the binary search. The result is printed based on whether the element is found or not.

ArrayList list = new ArrayList(); list.add(4); list.add(5); list.add(6); Iterator valueIterator = list.iterator(); while(valueIterator.hasNext()){ System.out.println(valueIterator.next()); } for this code output is 5, 6 I checked on onlinegdb, It's compiler fault or is it a bug?

it should be Iterable not iter-ratable .. similarly in another video on database isolation it should be repeatable read and not repeata-table read .. not sure if anyone else pointed out .. but the mistake tends to stick for new learners .. Please correct so that the new learners who are not familiar dont pick the wrong words

Hey thanks for pointing out. I will make sure of it buddy. Thanks for correcting

@poojapatole3573 3 ай бұрын
Thanks for the explanation but I wish you would have used the correct Interface name "Iterable" and not "Iteratable". I had to constantly keep reminding myself that it is "Iterable".

thanks for pointing out and sorry for that

It's confusing for new learners to hear iteratable when the actual word on the screen is iterable. Thank you.
