1. It will give false, because in java the == operator compares the reference, and if the object has the same reference then it will return true else false. In simple words it compares the address and if the address match then it returns true, else false.
Now, Here str1 and str2 are different objects and therefore == operator will return false because their address is different. In order to compare the data, we should rather use the equals method which compares the data.
2. Stack memory is always reversed at program startup.
Stack memory is a static memory and therefore it is set aside for execution of threads and function calls, whereas heap memory is dynamic memory.
Also, Stack is a static memory and is faster than heap, because is complex as it is dynamically allocated.
Push pop are not basic operation in heap memory before it has nothing to do with heap data structure.
Heap is not a hardware bases approach as it is dynamically allocated.
FOR ANY OTHER QUERY PLEASE COMMENT.
What is the output of this code ? String str1 = new String("cst8284"); String str2 =...
Given the following code fragment, what is the ultimate value of variable output? Dim str1 As String = "pro" Dim str2 As String = "baseball" Dim output As String = "MLB" Dim myVal As Integer = 5 output = str2.Substring(0,1) -Please provide the answer and how you got it Thank you.
java create java program that make stack with LinkedList and stack is implement iterator. When stack’s iterator call next(), it pop its data. here is the example of output //by user 5 1 2 3 4 5 //then output comes like this 5 4 3 2 1 Stack is empty. here is the code that i'm going to use class Stack<T> implements Iterator<T> { LinkedList<T> list; public Stack() { list = new LinkedList<T>(); } public boolean isEmpty() { return list.isEmpty(); ...
I have added a little Code but I need help with the rest. /** A class of stacks whose entries are stored in a chain of nodes. Implement all methods in MyStack class Main Reference : text book or class notes Do not change or add data fields */ package PJ2; public class MyStack<T> implements StackInterface<T> { // Data fields private Node<T> topNode; // references the first node in the chain private int numberOfEntries; public...
NO ONE HAS PROVIDED THE CORRECT CODE TO PROVIDE THE GIVEN OUTPUT. PLEASE PROVIDE CODE THAT WOULD CAUSE THE HW1.java TO PRINT THE RIGHT DATA.!!! The LinkedList class implements both the List interface and the Stack interface, but several methods (listed below) are missing bodies. Write the code so it works correctly. You should submit one file, LinkedList.java. Do not change the interfaces. Do not change the public method headers. Do not rename the LinkedList class. None of your methods...

how would I complete this code without calling any built-in java collection framework classes like ArrayList, LinkedList, etc? import java.util.Iterator; class CallStack<T> implements Iterable<T> { // You'll want some instance variables here public CallStack() { //setup what you need } public void push(T item) { //push an item onto the stack //you may assume the item is not null //O(1) } public T pop() { //pop an item off the stack //if there are no items on the stack, return...
What is output 1 in the code below? import java.util."; public class StackDemo { public static void main(String [] args) { Stack<Integer> intStack = new Stack<>(); Stack<Integer> tempStack = new Stack<>(); intStack.push(18); intStack.push(21); intStack.push(25); tempStack = intStack; while (!tempStack.empty() { System.out.print(tempStack.peek()+"");//output 1 tempStack.pop(); 3 System.out.println(); System.out.println(intStack.peek()); //output 2 25 18 21 • 25 21 18

I need help with this code This is what I need to do: Implement the Stack Class with an ArrayList instead of an array, including the following functions: • empty • push • peek • pop • overrided toString( ) function which returns all of the stack’s contents Things to note: • You no longer need a size. • You no longer need to define a constant DEFAULT_CAPACITY. Since ArrayLists grow dynamically. • Whenever possible, use ArrayList functions instead of...
