Sure! Here's a step-by-step guide to writing a Java program that counts the number of words with the first and last letter being the same:

1. Start by creating a new Java class. You can name it something like "WordCount".

2. Declare a public class named "WordCount" and include a main method inside it.

3. Inside the main method, create a Scanner object to accept user input. You can use the following code to do this:
```java
Scanner scanner = new Scanner(System.in);
```

4. Prompt the user to enter a string and store it in a variable. You can use the following code to do this:
```java
System.out.print("Enter a string: ");
String inputString = scanner.nextLine();
```

5. Split the input string into an array of words using the `split()` method. You can split the string by spaces using the following code:
```java
String[] words = inputString.split(" ");
```

6. Initialize a variable to keep track of the count of words with the first and last letter being the same. You can set it to 0 initially:
```java
int count = 0;
```

7. Iterate over each word in the array and check if the first and last characters are the same. If they are, increment the count variable. You can use the following code to do this:
```java
for (String word : words) {
if (word.charAt(0) == word.charAt(word.length() - 1)) {
count++;
}
}
```

8. Finally, print the count of words with the first and last letter being the same. You can use the following code to do this:
```java
System.out.println("Number of words with the first and last letter being the same: " + count);
```

9. Close the Scanner object to free up system resources. You can use the following code to do this:
```java
scanner.close();
```

10. Save and run the program. You can now enter a string and the program will count the number of words with the first and last letter being the same.

That's it! You have successfully written a Java program to count the number of words with the first and last letter being the same.
