Thank you! Base on all the methods 1-4, I want to write another method: The spec for method 5 A method to print a text-based histogram takes one parameter, an array of integers no return value Image 1 is the example of the expected output  Hint: it bacsically means: for example, if I have number 20 appears one time in my method, then we print a star(*) after number 20. I think we can use this method 4 to get this information.

Add another public method dblValue() to your 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 your client program to test this functionality; i.e. provide an output statement to display the double value of a fractionhere are my codes /** To change this license header, choose License Headers in Project Properties.* To change this template file, choose Tools | Templates* and open the template in the editor.*/package lab4; /**** @author engko*/public class Fraction {//Define the class Fraction// declaring instance variablesString res;private int num, denom; // default constructor to initialize instance…

Need help with following Java method: import java.util.Scanner; import java.lang.Math; public class CosineFromScratch { /* The following code demonstrates how to estimate the cosine of a number. Your assignment is to migrate the calculation of the cosine into a new static method named cosine. The method should take one double input and return one double output. Make sure to call the method from main and set the variable estimate equal to the returned value. */ public static void main(String[] args) { Scanner input = new Scanner(System.in); System.out.print("\nGive me a number: "); double x = input.nextDouble(); //Trying to find cosine of this number double correct_cos = Math.cos(x); //START HERE: The following code goes into //the method. //Source for the following: //https://austinhenley.com/blog/cosine.html double num_terms = 10; int div = (int)(x / Math.PI); x = x - (div * Math.PI); int sign = -1; double estimate = 1.0;…

Use Java program to add a method printReceipt to the CashRegister class. The method should print the prices of all purchased items and the total amount due. Hint: You will need to form a string of all prices. Use the concat method of the String class to add additional items to that string. To turn a price into a string, use the call String.valueOf(price). Also, the payment information will need to be the same as the price information.  Here is the CashRegister class: /**   A cash register totals up sales and computes change due.*/public class CashRegister{   private double purchase;   private double payment;    /**      Constructs a cash register with no money in it.   */   public CashRegister()   {      purchase = 0;      payment = 0;   }    /**      Records the sale of an item.      @param amount the price of the item   */   public void recordPurchase(double amount)   {      purchase = purchase + amount;   }    /**      Processes a payment received from the customer.      @param…
