In java Define a method named getWordFrequency that takes an array of strings, the size of the array, and a search word as parameters. Method getWordFrequency$()$ then returns the number of occurrences of the search word in the array parameter $($case insensitive$).$Then, write a main program that reads a list of words into an array, calls method getWordFrequency$()$ repeatedly, and outputs the words in the arrays with their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain less than $20$ words.Ex: If the input is:$5$ hey Hi Mark hi markthe output is:hey $1$Hi $2$Mark $2$hi $2$mark $2$
