Please help me do this in Java

Create a class called Forecast. Your Forecast class contains concepts associated with a weather forecast. Forecast does not contain a main method. Forecast should contain the following:

an attribute for the temperature

a floating point number from -100.0 through 150.0 degrees Fahrenheit

if no value or an invalid value is supplied, the default is 72.0

an attribute for the sky condition

a string

if no value is supplied, the default is clear

an attribute for the chance of rain

an integer from 0 100 that represents a percentage

if no value or an invalid value is supplied, the default is 0%

at least two constructors

accessors and mutators for all variables

methods that convert the temperature:

from Fahrenheit to Celsius

from Celsius to Fahrenheit

from Fahrenheit to Kelvin

from Kelvin to Fahrenheit

these methods return the converted temperature

these methods do not have print/output statements

a method that determines whether or not it rains

this method returns a boolean

this method does not have a print/output statement

a print() method that prints useful information about the forecast

Write a separate class (with a main method) that tests each of the methods in your Forecast class.
