Java programming....Queues
Create a method called "hasNodes". This returns true or false depending on if any nodes exist in the queue
public class AQueue{
private AQueue head = null;
private AQueue tail = null;
public boolean hasNodes(){ ......}
Homework Answers
See the code
below
public boolean hasNodes(){
if(head==null)
return true;
return false;
}
Explanation: We can check if head is null or not. If head
is not null that means few nodes exists otherwise return
false.

Create a program named NonZeroNumQueue.java then copy the contents from NonZeroNumQueue.txt. Then implement enqueue method. To get credit, DO NOT add or alter any data members/methods except the enqueue(int num). The NonZeroNumQueue will NOT accept zero, which mean you can enqueue any whole numbers EXCEPT 0(zero). You have already noticed that the queue is NEVER full, so the isFull() always returns false. given NonZeroNumQueue.txt public class NonZeroNumQueue{ private int[] data; private int total; private int front; private int tail; public...

java programming.
One. Write a method public boolean hasOnlyoddDigits(int n) that returns true if its parameter n contains only odd digits (1, 3, 5, 7, or 9), and returns false otherwise. Zero is counted as an even digit whenever it appears inside the number. Remember that for a positive integer n, the expression (n % 10) gives its last digit, and the expression (n / 10) gives its other digits. Correct answer true false false false 357199 7540573 97531000

Define a public method that is called isPrime() that returns a boolean and implements the Sieve of Eratosthenes method. Define a public method that is called numberOfPrimes() that returns the number of prime numbers between 2 and the private attribute value. Show this object in a main method that allows the user to interact with all the public methods of your class. Make a class called MyNumber with an integer private attribute. Make a constructor that defines an integer parameter...

Data Structures - Singly Linked Lists You will add a method swapNodes to SinglyLinkedList class (below). This method should swap two nodes node1 and node2 (and not just their contents) given references only to node1 and node2. The new method should check if node1 and node2 are the same node, etc. Write the main method to test the swapNodes method. You may need to traverse the list. package linkedlists; public class SinglyLinkedList<E> implements Cloneable { // ---------------- nested Node class...

Write a method in the HashIntSet class called addAll that accepts another hash set as a parameter and adds all of the elements from the other set into the current set. For example, if the set stores [-5, 1, 2, 3] and the method is passed [2, 3, 6, 44, 79], your set would store [-5, 1, 2, 3, 6, 44, 79].
