example code this, (this interview question asked me recently) list linkelements = driver.findelements(by.tagname("a")); list represents ordered list of objects, meaning can access elements of list in specific order, , index too. can add same element more once list. list allows null elements , can have many null objects in list you result in particular order 1 one. allow add duplicates. our result can have duplicates need in automation , if requirement different , not need duplicates can use other collection type.if use set not allow duplicates , it's unorder presentation of object. we use list because when using findelements() instead of findelement() expecting locator return more 1 element(not in every case or scenario). it's practice use list our data saved in list in ordered manner can use them properly. generally using list in below manner:- list<webelement> alloptions = dropdown.findelements(by."our locator"); ( webe...
