In the lecture we studied IntStack, a class that implements a static stack of integers. Write a template that will create a static stack of any data type. Demonstrate the class with a driver program. #pragma once class IntStack{private: int *stackArray; int stackSize; int top; public: IntStack(int size); void push(int num); void pop(int &num); bool isFull(); bool isEmpty();}; Queue Exceptions: Modify the static queue class provided in our lecture as follows. Make the isFull and isEmpty member functions private. Deﬁne a queue overﬂow exception and modify enqueue so that it throws this exception when the queue runs out of space. Deﬁne a queue underﬂow exception and modify dequeue so that it throws this exception when the queue is empty. Rewrite the main program so that it catches overﬂow exceptions when they occur. The exception handler for queue overﬂow should print an appropriate error message and then terminate the program. #include…
In Java, Question 15: Answer the following questions You are asked to Implement an ADT for MyQueue. The following is a class definition of a linked list Node: class Node { String content; Node next; } The following is a class definition of a linked list MyQueue: class MyQueue { Node head; } Implement the following methods for your class MyQueue. a) Constructor that does not requre any parameters b) Constructor that accepts a parameter of type MyQueue and creates a new instance of MyQueue that is a clone of the one passed as parameter c) public int AppendCopy method that accepts a single parameter of type MyQueue and clones all elements from the MyQueue instance passed as a parameter and appends them to the instance on which we called the method. Return the number of elements that are cloned and appended d) public int FindElements(String filter) - finds all elements that match the filter and returns their count e) overload the FindElementsmethod to include a…
Implement PokerValue as specified in textbook page 417, problem 33(a). Your implementation must include following: 1. At least one ADT type selected from textbook files such as Stack, Queue, Collection and List for storing the poker hand. 2. Use only CardDeck.java to hold deck of cards, and Card.java to represent each card. GUI is not required. 3. Default constructor to create a five-card poker hand from CardDeck.java. Make sure the poker hand is implemented with one of the textbook ADT as set forth above. 4. Overloaded constructor accepts an array of five cards to initialize one poker hand. 5. toString() method outputs in the same format as shown in SampleActualOutput.txt 6. You may add other methods as necessary. 7. Test your PokerValue.java with supplied PokerGame.java. Submit PokerValue.java
in java, The following is a class definition of a linked list Node:class Node{int info;Node next;}Assume that Node's constructor receives no parameters. For each line of the code below, explain what memory is being allocated by JVM (Java Virtual Machine). int counter = 0; double dd; String str = “New Label”; Node myNode; myNode = new Node();
Write an iterable Stack client that has a static method copy() that takes a stackof strings as argument and returns a copy of the stack. Note : This ability is a primeexample of the value of having an iterator, because it allows development of such functionality without changing the basic API.
java /* Practice Stacks and ourVector Write a java program that creates a stack of integers. Fill the stack with 30 random numbers between -300 and +300. A)- With the help of one ourVector Object and an additional stack, reorganize the numbers in the stack so that numbers smaller than -100 go to the bottom of the stack, numbers between -100 and +100 in the middle and numbers larger than +100 in the top (order does not matter) B)- (a little harder) Solve the same problem using only one ourVector object for help C)- (harder) Solve the same problem using only one additional stack as a helper */ public class HWStacks { public static void main(String[] args) { // TODO Auto-generated method stub } }
Create a TestStack project. Add a Stack class with all of the methods implemented and commented (constructor, push, pop, is empty, clear, peek, toString). Create a TestStack class with main(). main() should use your Stack class to do one of the following: OPTION A) Use your stack class to reverse a user inputted string. A palindrome is a word that reads the same backwards as it does forwards. For example, madam is a palindrome, hello is not. Use your stack class to test if an input string is a palindrone or not. OPTION B) Use your new Stack to add a function that checks for balanced parenthese in an equation. Use these three equations, plus one of your own to test your code. ((3^2 + 8)*(5/2))/(2+6) ((3^2 + 8)*(5/2))/(2+6)) (((3^2 + 8)*(5/2)/(2+6) When encountering a left parenthese, push it on the stack. Pop one off when you encounter a right parenthese. Return true or false depending if parentheses are balanced or not (stack is empty after last right parenthese causes a…
The implementation of a queue in an array, as given in this chapter, uses the variable count to determine whether the queue is empty or full. You can also use the variable count to return the number of elements in the queue. On the other hand, class linkedQueueType does not use such a variable to keep track of the number of elements in the queue. Redefine the class linkedQueueType by adding the variable count to keep track of the number of elements in the queue. Modify the definitions of the functions addQueue and deleteQueue as necessary. Add the function queueCount to return the number of elements in the queue. Also, write a program to test various operations of the class you defined.
IN JAVA Suppose that in the array-based stack, the array doubles in size after multiple push operations. But later on, fewer than half of the array’s locations might actually be used by the stack due to pop operations. Revise the implementation so that its array also can shrink in size as objects are removed from the stack. Accomplishing this task will require two new private methods, as follows: The first new method checks whether we should reduce the size of the array: private boolean isTooBig() This method returns true if the number of entries in the stack is less than half the size of the array and the size of the array is greater than 20. The second new method creates a new array that is three quarters the size of the current array and then copies the objects in the bag to the new array: private void reduceArray() Implement each of these two methods, and then use them in the definition of pop()
Answer the given question with a proper explanation and step-by-step solution. Hello team, Need some help with problems below using the langauge JAVA. I need to modify the CalcParser class provided below. I need this to produce a string containing commands to evaluate the expression on a stack machine. For example, if you give the command java CalcParser 1+2*3, the output should be a sequence of stack commands such as this: push 1.0 push 2.0 push 3.0 multiply add 7.0 For the command java CalcParser (1+2)*3, on the other hand, it should print a sequence like this: push 1.0 push 2.0 add push 3.0 multiply 9.0 CODE:public class CalcParser { private CalcLexer lexer; private String errorMessage = null; private double value; public CalcParser(String s) { lexer = new CalcLexer(s);errorMessage = lexer.getErrorMessage();if (errorMessage != null) return; value = parseExpression();if (errorMessage != null) return; match(CalcLexer.EOLN_TOKEN);if (errorMessage != null) return; } public String…
rite a method called samePosition in a class called StackExt that receives two parameters st1 and st2 of type ArrayStack and a third parameter pos of type int. The method returns true, if stack st1 and st2 contains the same value in position pos. Otherwise, the method returns false. Assume that both stacks st1 and st2 contain same number of elements. Assume that the position of the top element is 0 and increases by 1 for each subsequent element. The elements of both stacks st1 and st2 must remain in the original relative positions in the stacks at the end of the method. Use common stack operations only such as push, pop, peek, isEmpty, constructor and copy constructor. You can create temporary objects of type ArrayStack in your method. Example: top st1: 4 5 3 10 8 st1: 5 9 4 10 1 If the pos is 3, then both stacks contain 10 in position 3. The method returns true. If the pos is 1, then st1 contains 5 and st2 contains 9 in…
Im trying to figure out a java homework assignment where I have to evaluate postfix expressions using stacks and Stringtokenizer as well as a isNumber method. when I try to run it it gives me an error. this is the code I have so far: static double evaluatePostfixExpression(String expression){ // Write your code Stack aStack = new Stack(); double value1, value2; String token; StringTokenizer tokenizer = new StringTokenizer(expression); while (tokenizer.hasMoreTokens()) { token = tokenizer.nextToken(); if(isNumber(expression)) { value1 = (double)aStack.pop(); value2 = (double)aStack.pop(); if (token.equals("+")) { aStack.push(value2+value1); } else if (token.equals("-")) { aStack.push(value2-value1); } else if (token.equals("*")) { aStack.push(value2*value1); } else if (token.equals("/")) { aStack.push(value2/value1); } } }…
