Java Netbeans 6. Inside class StaticMethods, create the OVERLOADED static method squareNumber shown be-low that takes as a parameter a number of type double and returns the number squared asdouble. Call this method from the main method of class Lab14 and print the result. Do you seewhat makes Java distinguish overloaded methods at invocation? The argument(s) passed to themethod of course.26public static double squareNumber( double number)27 ESystem.out.println( "DOUBLE was called");return number * number;}2829307. Inside class StaticMethods, create the static method cubeNumber as shown below that takesas a parameter a number of type double and returns the number squared, as double. Call thismethod from the main method of class Lab14 and print the result. Please NOTE how themethod cubeNumber, calls the method squareNumber. Look ta the comments inside themethod.public static double cubeNumber( double number){return number * squareNumber( number );3132 D// StaticMethods.squareNumber is also correct as shown in comment below//return number * StaticMethods.squareNumber( number );}8. Inside class StaticMethods, create the static and OVERLOADED method cubeNumber thattakes as an argument an integer and returns a double. Test it from main.9. Inside class StaticMethods., create the static and OVERLOADED method cubeNumber thattakes as an argument a String and returns a double. Test it from main.10. Inside class StaticMethods, create the static method menu that displays a menu for the userto select 's' or 'c'. The method returns the character entered, ONLY when the user types 's'or 'c', otherwise prints a message and stays in a loop. Test it from main().public static char menu()3839 EString s = "";do{System.out.println("type S\\s to square a number:" );System.out.println("type C\\c to cube a number:" );S = new404142434445Scanner( System.in).next();46if ( "c".compareToIgnoreCase(s ) != 0 && "s".compareToIgnoreCase(s) != 0 )System.out.println("\tplease enter a valid character" );4748}while ("c".compareToIgnoreCase(s ) != 0 && "s".compareToIgnoreCase(s) != 0 );return s.charAt(0);49505152}

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:" + +…
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 number
In Public Class, create a static void method called Info_AHW that takes 3 parameters - an int and two double. When the method is called, we pass along the age (A), then the height (H), and then the weight (W), which is used inside the method to print the person's age, then the height and then the weight. NOTE: The Print out must follow the output below Afterward, in the main method, get the User input using the Scanner class to get the three input - the int age, the double height and the double weight. Then, call your Info_AHW method and pass your arguments (age, height, weight) into that method. Hint: When getting the int input, use -> sc.nextInt(); When getting the double input, use -> nextDouble(); Input: 5 65.5 70.2 Output: Your age is 5 ; your height is 65.5 ; and your weight is 70.2 Note: -There is a single space between every word and semicolon -There is no space at the end
a) Design and implement a Comparable Java class to represent a Rational number such as3/2. Your class will have the following methods as well as any other methods necessary (setters, getters, etc.). - A constructor that takes all parameters (numerator, denominator), - A function that returns the number of existing Rational objects, - Override the tostring method, - Methods for adding and multiplying Rational objects, - Your methods will throw exceptions if there are problems. b) Write another class to test your Rational class including the exceptions.
For beginning Java, here is my assingment " 1. Define a Java class named “Appointment” that contains a day, a month and adescription of the appointment (string). It should provide at least a method named“hasTheSameDate” that will compare with another Appointment object andreturn true if it has the same date (day and month) and false otherwise. It shouldalso have the toString() method to return a string in the format of“mm/dd: description” such as “6/1: Meet with John”2. Write the main method to show how you can create Appointment objects, call thehasTheSameDate() method and print out the “Appointment” information: a. Ask the user for input for 2 appointment objects. b. Print the 2 objects. c. Call hasTheSameDate() to compare the 2 objects and tell the user if they are the same or different."Here is my code, and I don't know on what is wrong with my code: " import java.util.Scanner; class Appointment { private int day; private int month; private String…

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 +…
Redefine the equals method of the class Date (Display 4.13) so that it hasa parameter of type Object and follows the other guidelines we gave for anequals method. (Remember, you should use getClass(), not instanceof.)
In Java, Use the Phone class as a baseline, and write a method isUSA. It should return true if the country code is 1 and false otherwise. Also expanding the Phone class, write a method that determines the location of an area code. It should return the name of the area code's city. For example, if cc = 1 and area code = 510 East Bay Area, 650 SF Peninsula, 415 San Francisco, 408 South Bay Area. For this assignment, use literal strings as return values.
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: 3
Add another public method dblValue() to the Fraction class which returns the double precision approximation value of the fraction. That is, the floating point result of actually dividing numerator by denominator. N.B. this method does not do any display itself, but can be called by a client program to be used in an output statement. Eg: if a client has a fraction frac that represents 1 / 2,then a method call to frac.dblValue() should return the double number 0.5.Use the client program to test this functionality; i.e. provide an outputstatement to display the double value of a fraction. import java.util.ArrayList;import java.util.Scanner; //Define the class Fractionclass Fraction{private int n, d;public Fraction(){//Initialize the valuesthis.n = this.d = 0;}public Fraction(int n, int d){//Initialize the variablesthis.n = n;this.d = d;}//Define the getter function getNum() that returns the numeratorpublic int getNum(){//Returns numeratorreturn n;}//Define the getter function getDen()…
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);…
Write a program that calls methods for each of the following mini problems from its main method. Us a single Scanner for the program declared in the class asprivate Static Scanner keyboard = new Scanner(System.in); Write a method that reads a line of text from the keyboard and then displays the line, but with the first occurrence of hate changed to love. For example, a possible sample dialogue might beEnter a line of text.I hate you.I have rephrased that line to read:I love you.You can assume that the word hate occurs in the input. If the word hate occurs more than once in the line, your program will replace only its first occurrence. Write a method that asks the user to enter a favorite color, a favorite food, a favorite animal, and the first name of a friend or relative. The program should then print the following two lines, with the user’s input replacing the items in italics: I had a dream that Name ate a Color Animal and said it tasted like Food!For example, if the user entered…
