Write a class that contains the following two methods: /** Convert from Celsius to Fahrenheit */ public static double celsiusToFahrenheit(double celsius) /** Convert from Fahrenheit to Celsius */ public static double fahrenheitToCelsius(double fahrenheit) The formula for the conversion is as follows: fahrenheit = (9.0 / 5) * celsius + 32 celsius = (5.0 / 9) * (fahrenheit – 32) Write a test program that invokes these methods to display the following table: NOTE: Celsius starts at 40 and should be converted to Fahrenheit, on the same line Fahrenheit starts at 120 and should be converted to Celsius Do not forget to Introduce your Program to the user with descriptive information. Do not forget to include a block Comment header at the start of your Source Code.

Create a class with name savingaccont.In this class you have to write the static method having name CalculteFutureValue which takes three parameters of type double along with return type double.This function should implement the formula given below.The formula, which is known as the future value formula, is:F = P * (1 + i)tThe terms in the formula are as follows: F is the future value of the account after the specified time period. P is the present value of the account. i is the monthly interest rate . t is the number of months . Write Driver class which contains main function that prompts the user to enter the account’s present value, monthly interest rate, and the number of months that the money will be left in the account. The program should pass these values to a function named CalculteFutureValue that returns the future value of the account, after the specified number of months. The program should display the account’s future value.

Create a class IndependenceUSA and write code which asks the user to enter text that contains the American Independence day ( July 4th 1776). Read the date using the method next() 3 times. The user should enter the Independence day in the order month, day, year as shown in the first two runs below( we are not case sensitive) . Use the String method compareToIgnoreCase() to test the validi-ty of the date and print “Hurrah!” if the date entered is correct, or “No, no , no! Incorrect!” if the date incorrect is incorrect, or of the date entered in the wrong order. In other words, you compare your input to “July” , “4”, “1776” , in that order and you don't case for capital or small case letters.

(Look at its methods - what is it capable of doing?) what is the purpose of the itemCount variable? In Java, the length of an array cannot be changed once it is created. If you want to extend the length of an array, you have to create a…
