Implement unique method that takes an ArrayList as input and returns an ArrayList with exactly a single occurrence of each element from the input list. For example, if the input list contains 5, 6, 7, 6, 3, 5, 5, 4 then the output list should have 5, 6, 7, 3, 4. Note: (1) You may assume that the ArrayList has a specific type of elements in it. In the class, we assumed it to have String type values. (2) You may only work with ArrayList(s).

Using JAVA, write a method that modifies an ArrayList<String>, moving all strings starting with an uppercase letter to the front, without otherwise changing the order of the elements. Write a test program to demonstrate the correct operation of the method.

how would you do this in a simple way? this is for a non graded practice lab

Define and implement a class named WordList similar to the MyArray class in the lectures thepast 2 weeks. Your WordList class should have the following data members and methods:data members:String[] list : array of n words (assume 1 ≤ n ≤ 20)int n : number of words in listmethods:1. WordList() - constructor for WordList class2. read() – read a sentence consisting of English words using a .nextLine() statement,break each word off the sentence, and save the words in array with one word in eacharray element keeping the relative order of the words unchanged.3. print() – use the array contents to print the word list4. sort() – sort the words in the array in alphabetical order using the insertion sortmethod.For example, if "To be or not to be, that is the question." is entered for the initial sentence:1. read() will build array {"To", "be", "or", "not", "to", "be", "that", "is", "the","question"}2. print() will use the array contents to print:To be or not to be that is the question3. sort()…
