+/* Write a class WordCheck that is supposed to check if words that are valid. A word is considered valid if it’s within the max and min limit range, and does not contain a certain string.
+Constructor that accepts 3 parameters, max and min length of a valid word, and a String that isn’t allowed in the words.
+Constructor that accepts 1 String parameter that isn’t allowed in the word; min and max lengths are defaulted to 5 and 12 in this case.
+Method isValid that accepts a String word and returns true if word is valid, false otherwise.
+An accessor method getValidCount that returns the number of valid words checked so far.
+Accessors and Mutators for max, min, String not allowed
+Example of class runs:
+WordCheck W1 = new WordCheck(4, 8, “$”);
+W1.isValid(“Hi”); //returns false as word is too short
+W1.isValid(“Hello”); //returns true as word is valid
+W1.isValid(“Hibernate”); //returns false as word is too long
+W1.isValid(“$Bills”); //returns false as word contains “$”
+W1.isValid(“Monday”); //returns true as word is valid
+W1.getValidCount(); //return 2 for two valid words so far
