Fill In The Blank. Hint: look at the declaration of a HashMap in the code above. What do we declare for key and value? Because a HashMap requires both keys and values, we must provide the declare it. for both the key and the value when we

Java Code: Build the two variable classes that we need: InterpreterDataType and a subclass InterpreterArrayDataType. I will abbreviate these as IDT and IADT. IDT holds a string and has two constructors - one with and one without an initial value supplied. IADT holds a HashMap<String,IDT>. Its constructor should create that hash map. We will use these as our variable storage classes as the interpreter runs. Let's start the interpreter itself. Create a new class (Interpreter). Inside of it, we will have an inner class - LineManager. We will also need a HashMap<String,IDT> that will hold our global variables. We will also have a member HashMap<String, FunctionDefinitionNode> - this will be our source when someone calls a function. The LineManager should take a List<String> as a parameter to the constructor and store it in a member. This will be our read-in input file. It will need a method : SplitAndAssign. This method will get the next line and split it by looking…

Each of the iterators must implement the java.util.Iterator interface by providing the two public methods hasNext () and next(). The Iterator interface also lists two additional methods, remove () and forEachRemaining (). These are marked as default, so the interface itself does not require implementation. Of these methods, this assignment only requires you to implement the remove () method of the linked list iterator. 1 ArrayList iterator This is an external iterator, meaning it is a public class named ICS211ArrayListIterator, and and the code is not part of the ArrayList class. Your ICS211ArrayListIterator class should have a constructor ICS211ArrayListIterator(java.util.ArrayList gives access to all the elements of the array list. This array must be saved as the value of a class variable of the iterator. data). The constructor must call one of the two toArray methods of ArrayList to obtain an array that Other than this single call to java.util.ArrayList.toArray in the constructor,…

7- question What keys and values are contained in the following map after execution of the following piece of code? Map map = new HashMap (); map.put (8, "Eight"); map.put (41, "Forty-one"); map.put (8, "Ocho"); map.put (18, "Eighteen"); map.put (50, "Fifty"); map.put (132, "OneThreeTwo"); map.put (28, "Twenty-eight"); map.put (79, "Seventy-nine"); map.remove ( 41); map.remove (28); map.put (28, "18"); map.remove (18); a. {8=Eight, 41=Forty-one, 8=0cho, 18=Eighteen, 50=Fifty, 132=OneThreeTwo, 28=Twenty-eight, 79=Seventy-nine, 28=18} b. {8=Eight, 8=Ocho, 50=Fifty, 132=OneThreeTwo, 79=Seventy-nine, 28=18} c. {50=Fifty, 132=DOneThreeTwo, 8=Ocho, 28=18, 79=Seventy-nine} d. {8=Eight, 50=Fifty, 132=OneThreeTwo, 79=Seventy-nine, 28=18}
