In  java, Write a method void popMult(int k) for the ArrayBoundedStack class which will pop k items from this. Throw a StackUnderflowException and don't pop anything if there are fewer than k items on this. This is a method of the ArrayBoundedStack class. DO NOT USE ANY OTHER METHODS OF THE ARRAYBOUNDEDSTACK CLASS.

You are given an array of n integers. Write a java method that splitsthe numbers of the array into two equal groups so that the GCD of all numbers in the second group is equal to one and the GCD of all numbers in the first group is not one. After splitting the numbers display the resulting groups as shown in the sample run below. Note: 1. The array has even size. 2. All elements of the array are less than 100. You are not allowed to define new arrays. 3. 4. You are not allowed to definenew methods or use methods from java libraries. Sample run of the method: Inputarray: (6,7,9,4,3,2} Output Group two: (7,9,3} Group one: (2,4,6} I Ignore Order of numbers. Order is not important //Ignore Order of numbers. Order is not important

Java Problem  Create an object of type FitnessExperiment that stores an array ofStepsFitnessTracker, DistanceFitnessTracker, andHeartRateFitnessTracker objects. In the FitnessExperiment class Add to your FitnessExperimentclass a method called getTotalDistance() that calculates the total distance walked by all theobjects stored in your FitnessExperiment. appropriately both values (total number of steps and total distance walked in that experiment) usingthe printExperimentDetails() method. FitnessExperiemnt.java  public class FitnessExperiment {FitnessTracker[] fitnessTrackers;public static void main(String[] args) {FitnessTracker[] trackers ={ new StepsFitnessTracker("steps", new Steps(230)),new StepsFitnessTracker("steps2", new Steps(150)),new StepsFitnessTracker("steps2", new Steps(150)),new HeartRateFitnessTracker("hr", new HeartRate(80)),new HeartRateFitnessTracker("hr", new HeartRate(80)),new DistanceFitnessTracker("dist1", new Distance(1000)),new DistanceFitnessTracker("dist2",…

Needs to be written in java: Write a program with a main() method that asks the user to input an integer array of 10 elements.Next, create three methods described below. From inside your main() method, call each of thethree methods described below and print out the results of the methods 2, 3, which return values.1. printReverse() - a method that receives an array of integers, then reverses the elements ofthe array and prints out all the elements from inside the method. Print all in one lineseparated by commas (see sample output below).2. getLargest() – a method that receives an array of integers, then returns the largest integervalue in the array. (print result from main())3. computeTwice()- a method that receives the previously reversed array of integers, thenreturns an array of integers which doubles the value of each number in the array (see thesample output below). (print result from main())Sample output:Enter a number:22Enter a number:34Enter a number:21Enter a number:35Enter a…

Write all the code within the main method in the TestTruck class below.  Implement the following functionality.  Construct two Truck objects: one with any make and model you choose and the second object with gas tank capacity 10. If an exception occurs, print the stack trace. Print both Truck objects that were constructed.      import java.lang.IllegalArgumentException ;   public class TestTruck {         public static void main( String[] args ) {                    // write your code here

In Java, please. Complete the Course class by implementing the findStudentHighestGpa() method, which returns the Student object with the highest GPA in the course. Assume that no two students have the same highest GPA. Given classes: Class LabProgram contains the main method for testing the program. Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here.) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: getGPA() returns a student's GPA.) Note: For testing purposes, different student values will be used. Ex. For the following students: Henry Nguyen 3.5 Brenda Stern 2.0 Lynda Robison 3.2 Sonya King 3.9 the output is: Top student: Sonya King (GPA: 3.9)   LabProgram.java import java.util.Scanner; public class LabProgram {    public static void main(String args[]) {       Scanner scnr = new Scanner(System.in);        Course course = new Course();      int…

I really need help in this please. Can you write in JAVA? Thank you

Write a class ArrayClass, where the main method asks the user to enter the four numbers. Create a method printArray that prints the array whenever required (use Array.toString method). Make the program run as shown in the Sample Run below. Use Array.sort, Arrach.bianrySearch, Array.equals

Given main(), define the Team class (in file Team.java). For class method getWinPercentage(), the formula is:wins / (wins + losses). Note: Use casting to prevent integer division. For class method printStanding(), output the win percentage of the team with two digits after the decimal point and whether the team has a winning or losing average. A team has a winning average if the win percentage is 0.5 or greater. Ex: If the input is: Ravens 13 3 where Ravens is the team's name, 13 is the number of team wins, and 3 is the number of team losses, the output is: Win percentage: 0.81 Congratulations, Team Ravens has a winning average! Ex: If the input is: Angels 80 82 the output is: Win percentage: 0.49 Team Angels has a losing average.
