Question

The program must be in JAVA and INCLUDE THE METHOD PROVIDED AND USE THE PROVIDED CODE

```java
import java.util.Scanner;

public class LabProgram {

    /* Define your method here */

    public static void main(String[] args) {
        /* Type your code here. */
    }
}
```

### Explanation:

This is a basic Java program template which uses the `Scanner` class for input. It contains a `LabProgram` class with two main sections:

1. **Method Definition Section:**
   - Comment `/* Define your method here */` indicates where you can define your methods.

2. **Main Method:**
   - `public static void main(String[] args) {}` is the main method where the program execution begins.
   - Within the main method, the comment `/* Type your code here. */` indicates where you should write the main body of your program code. 

The program imports `java.util.Scanner`, which is a utility class for reading user input.

**How to Write a Program to Read and Count Word Frequencies**

### Problem Description

Create a program that reads a list of words and outputs each word along with its frequency. The input starts with an integer indicating how many words follow. The list will always be fewer than 20 words.

### Example

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

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

### Implementation Tips

- **Arrays**: Use two arrays—one for storing words and another for their frequencies.
  
- **Method Definition**:
  Define and invoke a method to determine the frequency of each word.

**Method Signature:**
```java
public static int getFrequencyOfWord(String[] wordsList, int listSize, String currWord)
```

### Additional Notes

This task is a continuation from a previous chapter aiming to reinforce the use of methods in programming.
