For the following code I get an error:      Exception in thread "main" java.lang.Error: Unresolved compilation problems:      The type LinkedListIn is not generic; it cannot be parameterized with arguments      The type LinkedListIn is not generic; it cannot be parameterized with arguments <>        at linkedList.LinkedListTester.main(LinkedListTester.java:5) How can I fix it? package linkedList;   public class LinkedListTester { public static void main(String[] args) { LinkedListIn list = new LinkedListIn<>(); list.display(); list.add("Station 1"); list.add("Station 2"); list.add("Station 3"); list.add("Station 4");   // Print the linked list System.out.println("All Stations: " + list); // Accessing the first item System.out.println("First stop: " + list.getFirst()); // Accessing the last item System.out.println("Last stop: " + list.getLast()); // Removing the first item System.out.println("Left this station: " + list.removeFirst()); // Removing the last item System.out.println("Left this station: " + list.removeLast()); // Print the linked list System.out.println("Remaing station: " + list); } }

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,…

BuiltInFunctionDefinitionNode.java has an error so make sure to fix it.    BuiltInFunctionDefinitionNode.java import java.util.HashMap; import java.util.function.Function;   public class BuiltInFunctionDefinitionNode extends FunctionDefinitionNode { private Function<HashMap<String, InterpreterDataType>, String> execute;     private boolean isVariadic;       public BuiltInFunctionDefinitionNode(Function<HashMap<String, InterpreterDataType>, String> execute, boolean isVariadic) {         this.execute = execute;         this.isVariadic = isVariadic;     }       public String execute(HashMap<String, InterpreterDataType> parameters) {         return this.execute.apply(parameters);     }   }

Question 2: Using only LLNode java cass. Create a demo cass called LinkedlistDemo java. In this demo class, write a public static method called SumNode that receives a reference caled list of type LLNode of integer values. Your method shoukl sum all the nodes content and then add a new node contains the summation to the end of the list. For example, if the list contains: list Then after calling the method SumNode, the list becomes: list 36 11------- Paste SumNode code below this line Good Luck O
