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 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 does not exist in the 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
