Chapter 21.4, Problem 21.4.2CP
Program Plan Intro
Set:
Set is a data structure that is used for storing and processing non duplicate elements. It is an interface which extends collection and it is an unordered collection of objects.
Set is implemented by LinkedHashSet, HashSet or a TreeSet.
Hash Set:
In order to store its elements internally, the HashSet uses HashMaps and it implements the Set interface, backed by a hash table which is actually a HashMap instance.
ArrayList:
ArrayList provides dynamic arrays in Java and is a part of collection framework and is present in java.util package.

Remove Char
This function will be given a list of strings and a character. You must remove all occurrences of the character from each string in the list. The function should return the list of strings with the character removed.
Signature:
public static ArrayList<String> removeChar(String pattern, ArrayList<String> list)
Example:list: ['adndj', 'adjdlaa', 'aa', 'djoe']pattern: a
Output: ['dndj', 'djdl', '', 'djoe']
The last part of the code is not completed.
public static void displayArray(int[] list)
{
System.out.println("The sum resulting array is" + Arrays.toString(list));
}
}
