Hi

#Java

I have to write in Java generic <> method with ArrayList, LinkedList, HashSet and TreeSet . All methods need to be generic and need to test them

Please help me with this task

With ArrayList :

1. A generic method that replaces the third element of the ArrayList passed in the argument with another element (also passed in the argument).

2. A generic method that will increase the size of a given ArrayList by the specified value.

3. A generic method that will trim the capacity of the ArrayList to the number of elements it currently has.

4. A generic method that will clear the given ArrayList.

With LinkedList

1. A generic method that inserts a given item into the selected LinkedList index

2. A generic method that checks whether a given element exists in LinkedList

3. A generic method that will check whether a given LinkedList is empty or not

4. A generic method that will return a LinkedList of boolean, the method is to compare the elements of two LinkedLists - if two LinkedLists have all, e.g. 3 elements the same, then the LinkedList should look like this: [true, true, true].

With HashSet:

1. A generic method that will compare two sets and return a collection of only those items that are common to both sets

2. A generic method that will compare two HashSets - the method is supposed to return boolean.

TreeSet:

1. A method that will return and remove the last element of the TreeSet passed in the argument;

2. A method that will return an element lower than the object specified in the argument. In the Argument, you must also specify the given TreeSet
