- 1. Read the code below and complete tasks: public class CircleWithStaticMembers { double radius = 1; /* task 1: add a line of code to declare a static integer variable names numberOfObjects and initialize it to 0; */ /** Construct a circle with radius 1 */ CircleWithStaticMembers() { radius = 1; /* task 2: add a statement here so that each time this constructor is called, the number of static variable numberOfObjects increase by 1; */ } /* task 3: write a static method called getNumberOfObjects() which returns the value of numberOfObjects, write your code below; */ } // give the code below (assuming it’s in the main function) which calls the function getNumberOfObjectsModify the program below and add a public method called isZero() to the Fraction class. This method will determine if a Fraction represents a zero fraction. A zero fraction has a numerator == 0, no matter what the denominator is. Your isZero() method should return a Boolean resultindicating a zero fraction or otherwise. The method will be used by the client class to test whether the ‘calling fraction’ is equal to the number zero. Modify the program so that it now loops until a fraction representing zero is entered. //Import the essential package import java.util.ArrayList; import java.util.Scanner; //Define the class Fraction class Fraction { private int n, d; public Fraction() { //Initialize the values this.n = this.d = 0; } public Fraction(int n, int d) { //Initialize the variables this.n = n; this.d = d; } //Define the getter function getNum() that returns the numerator public int getNum() {…MethodsJava Write the appropriate method headings using the provided method name for the following processes:1.) Given the radius of a circle, print the area of a circle - printArea. 2.) Accept an integer, compute for the square of the number and return the String equivalent of the square of the number - makeString 3.) Calculate and return the sum of two decimal numbers - getSum. 4.) Given a student’s name and three test scores (of type int), print the student’s name and average test score - printStudentDetails. 5) Compute and return the average speed of a car, given the distance traveled (as type double) and traveling time (in hours and minutes, both of type int) - getAverageSpeed.
- Modify the program below to create a class that contains a static method; the method takes a string as a parameter and returns a boolean value indicating whether the parameter string has repeated characters in it or not. That is, return true if there is at least one character which appears more than once in the string. The string should be input by the .user import java .util.*; public class Main{public static void main(String args[]){Scanner scn=new Scanner(System.in); // Input the string from userSystem.out.println ( "Enter the String to check for duplicate characters:");String str = scn.next();// Check is variable to store bool value true// It will change to true if there are repeated charactersboolean check=false;for (int a = 0; a < str.length(); a++)for (int b = a + 1; b < str.length(); b++)if (str.charAt(a) == str.charAt(b))check=true;// If check is true then string has repeated characters if (check)System.out.println("The String " + str + " has repeated…Write a method orderFood() for the class Food that simulates ordering food. The method takes an integer as argument, which indicates the number of portions that are ordered. It then prints out a string showing the number of portions and the type of food ordered. The string needs to have the format as shown in the examples below. PythonFill in the parameters in the second method header for the overloaded method printCourse(). The number, type, and order of the method parameters are indicated in the method call from main(). Ex: If the input is 82 Ethics, then the output is: Ethics grade: 82 Immunology grade: 87 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 System.out.println(courseName+" grade: "+grade); } publicstaticvoidprintCourse(/* Your code goes here */) { System.out.println("Immunology grade: "+inputGrade); } publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intgrade; StringcourseName; grade=scnr.nextInt(); courseName=scnr.next(); printCourse(grade, courseName); printCourse(87); // Overloaded method called } }

Otherwise, the following error message must be printed and the number of shoppers present must be set to 0. There is an error in the number of shoppers. Use System.out.println to print the message. 2) The class must define a method called leaving that takes a single integer parameter. This represents the number of shoppers leaving the club at a particular point. You may assume that the parameter's value will always be greater than zero and you do not have to check for that. If the current number of clubbers is greater than or equal to the number leaving then the number of clubbers is decreased by the number leaving. Otherwise, the following error message must be printed and the number of clubbers present must be set to 0. There is an error in the number of shoppers.
