- You've been provided a software that purports to use hash coding to handle a collection of objects. If an item is present, the software should return its address, or if the item is not in the collection, it should return the location where it should be added. A manual that comes with the software describes criteria such as the intended format of table objects, table height, and the basic calling series. You just have the program's object code, not the source code. Make a list of the scenarios you'd need to check the program's functionality.USE the Node, StackArray, StackRef and Stack interface classes PROVIDED BELOW to create code that reads input from the sample Data File PROVIDED to solve PLEASE READ DIRECTIONs VERY CAREFULLY thanks for your help Data File2 3 4 + +12 6 / 4 * 4 +2 2 3 3 * * *7 5 / 5 + 17 -4 3 - 5 6 + 4 * -1 1 + 3 * 4 - 10 ^ public class Node <T>{ private T data; private Node<T> next; public Node(T data, Node<T> next) { this.data = data; this.next = next; } public T getData() { return data; } public Node<T> getNext() { return next; } } import java.util.Stack; public class StackArray<T> implements Stack<T> { private T [] elements; private int top; private int size; public StackArray (int size) { elements = (T[]) new Object[size]; top = -1; this.size = size; } public boolean empty() { return top == -1; } public boolean…you're storing information about the users of a web-based application, which is to say that each user has a username that is a string of uppercase letters, lowercase letters, and digits. let's imagine that the most common operations are to add a new user to the application and to check whether a user already exists (given a username). A hash table would be an appropriate way to solve this problem because you know that a well-chosen hash function can lead to something akin to Θ(1) lookups and amortized Θ(1) insertions - suppose that you've chosen a hash function that sums the character codes associated with the characters in the username. Is the chosen hash function a good hash function?
- Using eclipse, write a Console Java program that inserts 25 random integers in the range of 0 to 100 into a Linked List. (Use SecureRandom class from java.security package.SecureRandom rand = new SecureRandom(); - creates the random number objectrand.nextInt(100) - generates random integers in the 0 to 100 range)Using a ListItreator output the contents of the LinkedList in the original order. Using a ListItreator output the contents of the LinkedList in the reverse order.When I try to run the following Java code on netbeans IDE, it says "erroneous tree type:scanner" and doesn't work.

There must be no error in the code at all. I need the code for ProgramNode.java. Don't give me irrelevant information. Java Programming: Make ProgramNode (derived from Node, of course) to do this. But instead of ArrayList or LinkedList of FunctionNodes, make a HashMap, using the function name as the key and the FunctionNode as the value. This will make it fast to find FunctionNodes by name later. The model of recursive descent should suggest some methods, here: function() processes a function. It expects a define token. Then an identifier (the name). Then a left paren. Then a list of 0 or more variable declarations. Then a right paren. Then an endOfLine. Then constants and variables. Then an indent. Then statements. Then a dedent. It returns a FunctionNode or null. parameterDeclarations() process the parameters and returns a…
