Question

Java programming - please see attched image for initial instruction before the following below.

Write a subclass of VowelSeparator that adds three additional methods and a constructor. The class should be named VowelSeparatorAndCounter.

Here are the methods to add:

void setString(String s) This method should replace the string stored by the object with s. If the argument is null then the method should throw an IllegalArgumentException. (This is an unchecked exception)

int getVowelCount() This method should return the number of vowels in the string.int getNonVowelCount() This method should return the number of characters in the string that are not vowels.

Write a static method that accepts an array of VowelSeparatorAndCounter objects and returns the total number of vowels contained in all of them. It should have the following signature:

public static int totalVowelCount(VowelSeparatorAndCounter[] a)

Write a class named VowelSeparator.
The class should have
one constructor that accepts a String argument. The class
should also have two methods for retrieving this string:
getString() and getVowelOnlyString(). Consider the code below,
which uses a StringSeparator object:
vs = new VowelSeparator("Abc, easy as 123");
System.out.println(vs.getString());
System.out.println(vs.getVowelOnlyString());
In this case the output should be:
Abc, easy as 123
Aeaa
Give the public constructor and methods the following
signatures
public VowelSeparator (String s)
public String getString()
public String getVowelOnlyString()
Feel free to add any instance variables or methods that you
need, as long as they are protected or private. Consider the
letters 'a', 'e', 'i', 'o', and 'u' to be vowels. Never mind 'y'. The
getVowelOnlyString method should return all the vowels in the
string, in their original order, and in upper or lower case as they
are found in the string.
