@@JavaTechies Thanks to you for sharing your experience. One suggestion, you can add these timestamp in the description so it will create chapters, which will be helpful for others.

[@JavaTechies]

@@aabhasjain96 sure, thank you

@@JavaTechies also as I can see you got the offer after this. Could you please tell the entire process ?

[@balajiThiyagarajan21]

good interview, for the last question on sequencing zero firt and non zero second, i would use stream.concat api and concat a two streams, one iwth zero and other non zero
Integer[] array = {4, 0, 3, 0, 2, 0, 1};
Integer[] result = Stream.concat(
Arrays.stream(array).filter(num -> num == 0),
Arrays.stream(array).filter(num -> num != 0)
).toArray(Integer[]::new);

[@JavaTechies]

Thank you so much for your answer, i appreciate 🙏😊

[@swarupcodes]

The interviewer is such a nice human being. Awesome questions too.

[@JavaTechies]

Thanks

[@deepak2all]

For last question on sequencing array elements, it can be done using deque
List input = Arrays.asList(1,3,0,4,3,0,7);
Deque deque = new LinkedBlockingDeque();
input.stream().forEach(i -> {
if(i==0) {
deque.addFirst(i);
} else {
deque.add(i);
}
});

[@JavaTechies]

Thanks

[@ManishTiwari-or8zt]

you can use TreeSet and add the element to it, find with treeset.last() method--> will give max result

[@ArunraajSingh]

@@ManishTiwari-or8zt but bro, Treeset stores values in sorted order, here we want is insertion order. right?

[@digvijay1228]

You could also use Linked list impl of double ended queue

[@suganya8810]

Awesome mansi .. your way of explaining things is really good... and your videos are very useful

[@garrybal719]

Good info..
Candidate seems very good with theoretical questions, however, when it comes to practical/coding/problem solving, seems pretty stuck or confused.

[@MrKishorekommula]

You have to implement all methods of abstract classs

[@javaspecialization1832]

Your Interview experience are very helpful mam. I have learned a lot from these interviews. Keep up the good work mam

[@JavaTechies]

Thank you so much

last question is perhaps on Insertion sort, i.e. in-place sorting

[@punyabikash3624]

Madam you are very good at your answers everything is perfect but this "So Basically" before every answers is headache...😂😂

[@JavaTechies]

Yeah, I improved now

[@jagadeeshbaskaran4881]

Please share java coding interview questions for telstra.

[@dips2805]

for the question asked at @35:36
we can have 2 int variable named as min and max.
and for every number generation whatever number stream generates, we can put this in max variable first
and after 2nd iteration put a check to compare a number if greater than what this variable already has.
if yes then replace the latest number in max.
if the number generates in 2nd iteration is less than the previous number , put this number in min variable.
at the end of the iteration you will get the max and min numbers in those variable.

[@JavaTechies]

Thanks, good approach and we will be able to solve it in o(n).

[@0brajeshsharma]
