ADTStack myStack = new StackUsingArrays(); for(int i=5; i>0; i--) myStack.push(i); while(!myStack.isEmpty()) System.out.print(myStack.pop() + ", ");

Thank you. I see that this works, but I am trying to work with the stack operators. Can you show me how you would implement 'pop' and 'push' in this scenario?

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); } } }...

Hi, would you be able to assist me with problem in java code. ......Four new students have arrived at Hogwarts School of Witchcraft and Wizardry. The students will join one of the four houses, Gryffindor, Hufflepuff, Ravenclaw, and Slytherin. The sorting hat has gone missing so in the meantime students will provide a list of the houses they wish to join and the Houses will rank the students in the order they wish to choose. You have been tasked with creating a program to determine a stable match between the students and Houses. The students will get to select their house of choice one at a time. If a student selects a house that is already chosen but rates higher on the list for that house, they are paired to that house and the student who is now un paired will need to select a new house form their ranked list. The program will need each student's name and list of house preferences. Additionally, it will need each house’s name and ranked list of students. How you implement that...

Can you implement the StackADT.cpp, Stack.ADT , and StackMain.cpp files, please?

Create a computer programme to arrange objects in a stack so that the smallest ones are on top. Although you are allowed to utilise an extra temporary stack, you are not allowed to transfer the components into another data structure (such an array). The following operations are supported by the stack: push, pop, peek, and is Empty.

Java programming homework please help

OCaml Code: The goal of this project is to understand and build an interpreter for a small, OCaml-like, stackbased bytecode language. Make sure that the code compiles correctly and provide the code with the screenshot of the output. Make sure to have the following methods below: -Push integers, strings, and names on the stack -Push booleans -Pushing an error literal or unit literal will push :error: or :unit:onto the stack, respectively -Command pop removes the top value from the stack -The command add refers to integer addition. Since this is a binary operator, it consumes the toptwo values in the stack, calculates the sum and pushes the result back to the stack - Command sub refers to integer subtraction -Command mul refers to integer multiplication -Command div refers to integer division -Command rem refers to the remainder of integer division -Command neg is to calculate the negation of an integer -Command swap interchanges the top two elements in the stack, meaning that the...

You will create two programs. The first one will use the data structure Stack and the other program will use the data structure Queue. Keep in mind that you should already know from your video and free textbook that Java uses a LinkedList integration for Queue. Stack Program Create a deck of cards using an array (Array size 15). Each card is an object. So you will have to create a Card class that has a value (1 - 10, Jack, Queen, King, Ace) and suit (clubs, diamonds, heart, spade). You will create a stack and randomly pick a card from the deck to put be pushed onto the stack. You will repeat this 5 times. Then you will take cards off the top of the stack (pop) and reveal the values of the cards in the output. As a challenge, you may have the user guess the value and suit of the card at the bottom of the stack. Queue Program There is a new concert coming to town. This concert is popular and has a long line. The line uses the data structure Queue. The people in the line are objects...
