How to solve this question: Create an App class to accomplish the following requirements:

$$ Create four objects of type Passenger and add them to a passengerList of type ArraySortedList.

$$ Define a generic static method named removeDuplicatePassenger, which takes one parameter: passengerList of type ArraySortedList. This method is intended to remove, from the passenger list, redundant passenger objects that have the same seat number $($i$.$e$.$ if there are three passengers with the same seat number, you should keep the first one and delete the others$).$

Hint: Passengers must be sorted according to seat numbers, you have to create a temp list

then loop through the list using for

loop

if$($temp$.$contains$($passenger$)==$fals

e$)$

you can add the passenger to the

temp list

so you read list items one$-$by$-$one

if the item not exists in side temp

list

add the item to the temp list

if the item already exists in the

temp do not add it

after the for loop end

all unique items will be added to

the temp list $($WITHOUT USING THIS FOR LOOP$($for $($T passenger : passengerList$))$& PLEASE PLEASE USE THE HINTS I WROTE$)$
