- For all methods in each class (labeled), how do I write the JUnit 4 test(s) to test all methods? Full code is shown below: PunctuationNode.java (class) public class PunctuationNode implements Sentence { private String punctuation; private Sentence rest; /** * This is a constructor for class PunctuationNode. * * @param punctuation - a String. * @param rest - a String. */ public PunctuationNode(String punctuation, Sentence rest) { this.punctuation = punctuation; this.rest = rest; } /** * A method to get number of words. * * @return - a integer. */ @Override public int getNumberOfWords() { return this.rest.getNumberOfWords(); } /** * A method to get longest word. * * @return - a integer. */ @Override public String longestWord() { return this.rest.longestWord(); } /** * Returns a String that represents a sentence. * * @return - a Sentence. */ @Override public String toString() { return this.punctuation +…In Java In the Jackal class, complete the public method definition for setAge() with the integer parameter customAge. Ex: If the input is black Mia 3, then the output is: Color: black Name: Mia Age: 3Write a non-static method called average that accepts two integer parameters and returns their average as a double value. Overload the average method in the above such that if three integers are provided as parameters, the method returns the double value of all three.
- use the method setData(String,String,doule,int) to set the employee’s details; and the method getDetails() that will return a descriptive statement about the employee. import java.util.*;class Department { private int groupScore; private double groupAverage; private static int overallScore; private static double overallAverage; public Department(int r1,int r2,int r3,int r4,int r5) { Department.overallScore=Department.overallScore+r1+r2+r3+r4+r5; Department.overallAverage=Department.overallScore/10.0; this.groupScore=r1+r2+r3+r4+r5; this.groupAverage=this.groupScore/5.0; } public double getGroupAvergae() { return this.groupAverage; } public void displayAverage() { System.out.println("Overall Average:"+Department.overallAverage); } }public class Main { public static void main(String args[]) { Department d1=new Department(1,2,3,4,5); d1.displayAverage(); Department d2=new Department(5,4,4,4,1);…Define a Static method 'max' with return type as 'int' in class 'ProblemSolution' that take two numbers with type 'int'. Inside the 'max' method, compare the two numbers and return the maximum of the two numbers. Then, inside the 'main' method. Define two 'int' type numbers; the first number (num1) is equal to 5 and the second number (num2) is equal to 2. At the next line, call the 'max' method where its parameter input are the two numbers above, and assign the result of the method to the variable num3 (type 'int'). Finally, on the next line, print out -> "The maximum of " + num1 + " and " + num2 + " is " + num3 Output The maximum of 5 and 2 is 5 Where, There must be space between all the words and numbers. There should not any space after the last numberWrite java method fullName with a return type of void and accept a name. The method will display the abbreviation of the firstname and middle name except for the lastname. For example, if name is Yule Plaza Sanchez it will display: Y.P.Sanchez For example: Test Result fullName("Yule Plaza Sanchez"); Y.P.Sanchez fullName("Yule Josef Plaza Sanchez"); Y.J.P.Sanchez
- Is this overload constructor? But what is behavior methods? Do I need to add walk, feed and bark into the code? See code below: Overload constructor? public String getName() {return name;}public String getBreed() {return breed;}public int getAge() {return age;} package dog1; public class Dog1 { String name;String breed;int age;public Dog1(String name, String breed, int age) { this.name = name;this.breed = breed;this.age = age;}public String getName() {return name;}public String getBreed() {return breed;}public int getAge() {return age;}@Overridepublic String toString() {return ("My name is " +this.getName()+".\nMy breed and age are: "+this.getBreed()+","+this.getAge());}public static void main(String[] args) {Dog1 chico = new Dog1("Chico", "Pitbull",5);System.out.println(chico.toString());}} How can I add walk, feed and bark?To rectify the problem identified in the following program,add a public method called isZero() to 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. isZero() method should return a Boolean result indicating a zero fraction or otherwise. The method will be used by the client class (TestFraction.java) to test whether the ‘calling fraction’ is equal to the number zero. Modify old client class so that it now loops until a fraction representing zero is entered. //TestFraction.javaimport java.util.Scanner;//test programpublic class TestFraction{ public static void main(String[] args) { //create a Scanner object Scanner in = new Scanner(System.in); //create new fraction Fraction frac = new Fraction(); //declare numerator and denominator int n=1,d; System.out.print("Enter Fraction's Numerator: "); //input numerator n =…For this Bank Teller's program, your assignment is to add in methods after each case in Java using Netbeans 8.2.
- The following code is poorly structured. Rewrite it so that it has a better structure and avoids redundancy. To help eliminate redundancy, convert the code into a method named spending that accepts two parameters: a Scanner for the console, and a String for a single person's name, and prints the appropriate information about that person's bills. Your method could be called twice (once for John and once for Jane) to replicate the original code's behavior.java program Write the equals method for Circle2 which returns true when the radius and the color are the same as the parameter’s radius and color. The TestCircle2, Circle2 and GeometricObject2 classes are given as follows. public class TestCircle2 { public static void main(String[] args) { Circle2 c1 = new Circle2(2.3, "red"); Circle2 c2 = new Circle2(5.6, "white"); Circle2 c3 = new Circle2(2.3, "red"); System.out.println("c1 equals c2: " + c1.equals(c2)); System.out.println("c1 equals c3: " + c1.equals(c3)); System.out.println("c2 equals c3: " + c2.equals(c3)); } } class Circle2 extends GeometricObject2 { private double radius; public Circle2() { } public Circle2(double radius) { this.radius = radius; } public Circle2(double radius, String color) { this.radius = radius; setColor(color); } /** * Return radius */ public double getRadius()…In Java As discussed in the class, overloaded methods are two or more methods in the sameclass that use the same name but differ in the signature. Following are headings forthree overloaded findMinimum methods.int findMinimum(int a, int b, int c)double findMinimum(double a, double b, double c)double findMinimum(double a, double b, double c, double d).These methods should return the given arguments' minimum (smallest) value. Yourtask is to implement these static overloaded methods.public class Minimum{ public static void main(String args []) { int oneI = 50; // first number int twoI =14; // second number int threeI =18; // third number double oneD = 44.0; // first number double twoD =14.0; // second number double threeD =18.0; // third number double fourD =0.0; System.out.println("The minimum of" + oneI + ","+ twoI + "," + "and" +threeI + "is:" + findMinimum(oneI,twoI,threeI); System.out.println("The minimum of" + oneD + ","+ twoD + "," + "and" +threeD +"is:" + +…
