100%
The language is Java. The code provided is what I have however it is not outputting the correct number, only 0.
Transcribed Image Text:**Educational Resource: Character Counting Program**
**Objective:**
Given a line of text as input, output the number of characters excluding spaces, periods, or commas.
**Example:**
- **Input:**
`Listen, Mr. Jones, calm down.`
- **Output:**
`21`
**Note:**
Account for all characters that aren't spaces, periods, or commas (e.g., "r", "2", "!").
![```java
import java.util.Scanner;
public class LabProgram {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
String userText;
int i;
int length = 0;
// Add more variables as needed
userText = scnr.nextLine(); // Gets entire line, including spaces.
for (i = 0; i < userText.length(); ++i) {
if ((userText == " ") || (userText == ".") || (userText == ",")) {
++length;
}
}
System.out.println(length);
}
}
```
### Explanation
This Java program reads a line of text from the user, iterates through each character, and counts how many spaces, periods, and commas it contains. Here is a detailed explanation of the code:
1. **Import Statement**:
- `import java.util.Scanner;` imports the Scanner class, which is used to obtain input from the user.
2. **Class and Main Method**:
- `public class LabProgram` defines a public class named `LabProgram`.
- `public static void main(String[] args)` is the main method, which is the entry point for this program.
3. **Variable Declarations**:
- `Scanner scnr`: Creates a new Scanner object to read input.
- `String userText`: Declares a variable to hold the user's input.
- `int i`: A loop counter.
- `int length = 0`: This variable stores the count of spaces, periods, and commas in the input.
4. **User Input**:
- `userText = scnr.nextLine();`: Reads an entire line of input from the user, including spaces.
5. **Loop and Condition**:
- `for (i = 0; i < userText.length(); ++i)`: Iterates over each character in `userText`.
- `if ((userText == " ") || (userText == ".") || (userText == ","))`: Checks if the current character is a space, period, or comma. If true, increment `length`.
6. **Output**:
- `System.out.println(length);`: Prints the total count of spaces, periods, and commas in the user's input.
### Notes
- The logic used within the loop needs correction. The code intends](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8fe79bd2-2df3-45cc-abc0-ffa837cca5d8%2Fb0688262-9272-4c71-9750-93a1f83efcdc%2Fmpgcgkq_processed.png&w=3840&q=75)
