Use a two-dimensional array to store the vowel counts. The array’s firstcolumn holds the counts for the lowercase vowels, and the second column holds the counts forthe uppercase vowels.The user indicates the end of the input by pressing enter by itself. At that point, your programshould print, for each vowel, the total number of lowercase occurrences, the total number ofuppercase occurrences, and the total number of combined occurrences.Here are some implementation requirements:1. Use two separate files – one for a main driver method and one for a VowelCounter classthat keeps track of vowel counts.2. main – Repeatedly prompt the user to enter a line of text or press enter by itself to quit.Note that the stdIn.nextLine() method returns the empty string ("") if the user pressesenter by itself. For each entered line of text, call the processLine method.

- This method takes in an array of Strings. The method's task is to find out how many times the most common character frequency appears in all of the array's Strings. As an example, for the array ["mouse", "cat", "dog"], the method should return 9, since the characters "m", "u", "s", "e", "c", "a", "t", "d", and "g" appear only once and this frequency (1) appears 9 times. The character "o", appears twice. This frequency (2) appears only once. Therefore, 9 must be returned. Also, if a character appears multiple times in one String, you must count every occurrence. For example, in the word "houses", the character "s" appears twice. Therefore, each occurrence of "s" must be counted. If there is a tie at the completion of the method, you must still return how many times the most frequent character frequency occurred. Furthermore, in your implementation, you must make use of the Java Class Library's HashMap class in order to map particular characters to their respective frequencies. Note:…Write the following method to test whether all the points in the array points are on the same line: public static boolean sameLine(double[][] points) Write a program that prompts the user to enter five points and displays whetherthey are on the same line.
