Write a Java program that reads a string str and a word wrd $($another string but with no spaces$)$

as inputs and determines how many times wrd appears in the string str$.$

Programming requirements

You should read both str and wrd from the input in the main method. Make sure that you use

two separate lines to give the input and use scan.nextLine$().$

You should write a non$-$void method named countWord that accepts two strings, sentence

and word, as parameters. It should return the number of times word occurs in sentence. For

example, if the string sentence is

My favorite subject is Computers but that subject is harder than Math

although it is a subject known for a long time.

and the word is "subject", then the method should return $3.$ Make sure to use the String

method equalIgnoreCase $()$ so that the comparison of words is case insensitive.
