The input starts with an integer indicating the count of words that follow. The list will always contain fewer than 20 words.#### Example:- **Input:** `5 hey hi Mark hi mark`- **Output:** ``` hey 1 hi 2 Mark 1 hi 2 mark 1 ```#### Instructions:- **Hint:** Utilize two arrays: one for storing the words and another for storing their frequencies. - **Method Definition:** You are required to define and use the following method in your program: ```java public static int getFrequencyOfWord(String[] wordsList, int listSize, String currWord) ```- **Note:** This is a continuation of a previous lab that now necessitates using a method.This task will help in understanding array manipulations and method usage in programming.

The main objective of the java program is to read a text file that contains the size number of words in the file and print the frequency of the word in the file onto the java console window. The java program implements the method, getFrequencyOfWord as follows. public static int getFrequencyOfWord(String[] wordList, int listSize, String currWord) { //set count =0 int count=0; //Iterate over the wordList array for (int i = 0; i < wordList.length; i++) { if(wordList[i].equals(currWord)) //increment the count by 1 count++; } return count; }//end of the method The above method returns the frequency of the currWord passed as input to the method.Java program source code that demonstrates the method, getFrequencyOfWord : //LabProgram.javaimport java.io.File;import java.io.FileNotFoundException;import java.util.Scanner;public class LabProgram { public static void main(String[] args) { //declare variables String wordsList[]; int freqList[]; int n; int index=0; Scanner filescanner=null; //try-catch block try { //Open file for reading filescanner=new Scanner(new File("data.txt")); //read starting number n=filescanner.nextInt(); //create two arrays wordsList=new String[n]; freqList=new int[n]; //read data from file and insert into the wordsList array while(index<n) { String word=filescanner.next(); wordsList[index]=word; index++; } filescanner.close(); //calculate the method , getFrequencyOfWord to count //frequency of the each word for (int i = 0; i < freqList.length; i++) { int count=getFrequencyOfWord(wordsList, n, wordsList[i]); freqList[i]=count; } //print the wordsList and freqList for (int i = 0; i < n; i++) { System.out.println(wordsList[i]+" "+freqList[i]); } } catch (FileNotFoundException e) { System.out.println("File not found"); System.exit(0); } } /*The method, getFrequencyOfWord that takes an array of wordList, an integer listSize * and the current word as input arguments and then the method returns the count * of the occurences of the current word in the wordList as return value*/ public static int getFrequencyOfWord(String[] wordList, int listSize, String currWord) { //set count =0 int count=0; //Iterate over the wordList array for (int i = 0; i < wordList.length; i++) { if(wordList[i].equals(currWord)) //increment the count by 1 count++; } return count; }//end of the method} //end of the classThe input file, data.txt data: 5 hey hi Mark hi mark Screenshot of the sample output:

Computer Science

Write a program that reads a list of words. Then, the program outputs those words and 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 mark the output is: hey 1 hi 2 Mark 1 hi 2 mark 1 Hint: Use two arrays, one for the strings, another for the frequencies. Your program must define and call a method: public static int getFrequencyOfWord(String[] wordsList, int listSize, String currWord) Note: This is a lab from a previous chapter that now requires the use of a method.

### Program to Count Word Frequencies

This exercise involves writing a program that reads a list of words and outputs each word alongside its frequency of occurrence. The input starts with an integer indicating the count of words that follow. The list will always contain fewer than 20 words.

#### Example:

- **Input:**
`5 hey hi Mark hi mark`

- **Output:**
```
hey 1
hi 2
Mark 1
hi 2
mark 1
```

#### Instructions:

- **Hint:** Utilize two arrays: one for storing the words and another for storing their frequencies.

- **Method Definition:**
You are required to define and use the following method in your program:
```java
public static int getFrequencyOfWord(String[] wordsList, int listSize, String currWord)
```

- **Note:** This is a continuation of a previous lab that now necessitates using a method.

This task will help in understanding array manipulations and method usage in programming.
