Why did Sir use <>() while creating array list in if loop

#1

Jus t wanted to ask Why did Sir use <>() while creating array list in if loop but he did not use <> when creating a new ArrayList for recResult. Does <> not matter or I have missed something.

#2

hey @code_breaker-1001 <>definitely matters in the code however you can skip <>this in RHS.for eg.
ArrayList ar = new ArrayList<>(); is similar to ArrayList ar = new ArrayList();

#3

But then when do we use <> for declaring arraylist…

#4

hey @code_breaker-1001 It depends on you putting <> on RHS is not necessary so if you want add It otherwise dont

#5

ohk, then just what is the purpose of this <> in ArrayList then?

#6

hey @code_breaker-1001 <> specifies that the arrayList is a generic list means it can be of any type from int, boolean, long, char to even classes.

ohk Thank you…
