Write a Java program using Stack class to demonstrate the following activities: Create three empty stacks named stack1, stack2 and stack3 respectively. Push the numbers [6,4,9] into stack1 and [1,2,3] into stack2. Pop the top number of stack1 and top number of stack2 and multiply them. Then, push the multiplication result into stack3. Pop the top number of stack1 and top number of stack2 and divide them. Push the result of division into stack3. Print Stack1, stack2 and stack3. Print the largest number in stack3

10. Write a program which will rearrange and sort a stack of integer values, using two other stacks. The following algorithm describes how to do this: 1. Start with a stack of numbers named primary and two empty stacks named 1ower and higher. 2. Pop the first number from your primary stack and put it into the 1ower stack 3. Pop the next number from your primary stack, if it is smaller than the number you previously put into the lower stack, then add it to the lower stack, otherwise put it in the higher stack. 4. Repeat step 3 until the primary stack is empty. 5. Pop each of the elements from the lower stack and add them back into the primary stack. 6. Pop each element of the higher stack. If the value is greater than the value at the head of the primary stack, then add it onto the primary stack, otherwise add the number into the lower stack. 7. Repeat the process from steps 3 through to step 6 until both the higher and lower stacks contain no elements. At this point, the primary stack...

CPU Priority Scheduling-preemptive: Write a Java program to implement a priority scheduling algorithm that uses low number to represent high priority. Your program should first prompts the user to input a list of process ID, arrival time, burst time, and priority for each process to be run on the CPU. The list is terminated by 0 0 0 0 for the process ID, arrival time, burst time, and priority. The program output should draw a Gantt chart (as text) that shows the scheduling order of the processes using the Priority scheduling algorithm. Also print the turnaround time, response time, and waiting time for each process along with their average for all processes. Make sure to display very helpful messages to the user for input and output.

Java programming homework please help

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 } }

Please help with the following in Java Write a Java program create a stack with elements pushed 1, 2, 3, 4 and 5, removes the middle element. Note that you may use only push(), pop(), peek() and empty() methods of the stack.

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...

Write a Java program and screenshot of the output using Stack class to show the following points: a. Create three empty stacks named stackOne, stackTwo and stackThree respectively. b. Push the numbers [a, b, c, d] "for example [7, 5, 8, 22]" into stackOne and [w, x, y, z] "for example [5, 4, 2, 11]" into stackTwo. (Note: value of the numbers [a,b,c,d, etc] for each of the student should be different) c. Pop the top number of stackOne and top number of stackTwo and add them. Then, push the addition result into stack Three. d. Pop the top number of stackOne and top number of stackTwo and subtract them. Push the result of subtraction into stackThree. e. Print StackOne, stackTwo and stackThree. f. Print the largest number in stack Three
