Concept explainers

Array

The simplest way to start thinking about an array is as a collection, or a set of elements. In programming, these elements may be constants, variables, functions and pointers.

Question

public static ArrayList<Integer> findExactString(String s, ArrayList<String> myArray)
{
return null;
}
// Use the above method, findExactString, as a helper method to implement
addWithoutDuplication method.
The addWithoutDuplication method has the following properties:
1- It takes two arguments, a string s and an ArrayList myArray of type string.
2- It returns an integer which represents the number of occurrences of the string s in
myArray while attempting to add it.
3- If myArray is null, it returns -1
4- If adds the string s to the end of the ArrayList myArray if the string s is not
already there.
public static int addwithout Duplication(String s, ArrayList<String> myArray)
{
return -1;

in Jave create a method work() with the follow instructions: If the work() method is passed a non-null then it must return a new List that contains some or all of the elements in data. The elements of the new List must be aliases for (not copies of) the objects in the List it is passed. If there are no sign attributes (i.e., the array is null or has 0 elements) then the work() method must return an empty List. If any of the conditions represented by the sign attribute holds for a particular element that that element must be included in the result (i.e., the conditions must be combined using a logical OR). The elements in the returned List must be in the same order they appeared in the original List (though not all elements must be in the result). public List<T> work(List<T> g){

Write a public static method named allLessThanMean that will take an ArrayList<Integer> as an argument. This method will return an ArrayList<Integer>. When called and passed anArrayList, this method will return an ArrayList containing all the elements in the argument ArrayList that are less than the average of all the values in the argument ArrayList. The values in the returned ArrayList must be in the same order as they are in the argument ArrayList. Here are some examples: Example 1 Given: ArrayList<Integer> myList = new ArrayList<Integer>(); with these values {1, 2, 3, 4, 5}; allLessThanMean(myList) should return an ArrayList<Integer> with these values {1, 2} Example 2 Given: ArrayList<Integer> myList = new ArrayList<Integer>(); with these values {3, 7, 6, 2, 9, 0, 4, 8}; allLessThanMean(myList) should return an ArrayList<Integer> with these values {3, 2, 0, 4} Example 3 Given: ArrayList<Integer> myList = new…
