1. Create an application named StudentsStanding.java that allows you to enter student data that consists of an lID number, first name, last name, and grade point average. Have the program accept input until ZZZ is entered for the ID number. Depending on whether the student's grade point average is at least 2.0, output each record either to a file of students in good standing or those on academic probation.

Question

Please only answer number 1, I will post the two parts separately so for now, just do number 1, THANKS

The image displays the Java source code for a program intended to manage student standings using file operations. Below is the transcription of the code as it would appear on an educational website:

```java
import java.nio.file.*;
import java.io.*;
import static java.nio.file.StandardOpenOption.*;
import java.util.Scanner;
import java.nio.channels.FileChannel;

public class StudentsStanding {
    public static void main(String[] args) {
        Path goodFile = Paths.get("/root/sandbox/StudentsGoodStanding.txt");
        Path probFile = Paths.get("/root/sandbox/StudentsAcademicProbation.txt");

        // Write your code here
    }
}
```

### Explanation:

#### Code Breakdown:
- **Imports:**
  - `java.nio.file.*`: This package is used for file and directory operations.
  - `java.io.*`: Provides for system input and output through data streams, serialization, and the file system.
  - `java.nio.file.StandardOpenOption.*`: Specifies how files are opened.
  - `java.util.Scanner`: Used for reading input, typically used for reading user input.
  - `java.nio.channels.FileChannel`: Provides file input/output operations.

- **Class Definition:**
  - `public class StudentsStanding`: Defines a public class named `StudentsStanding`.

- **Main Method:**
  - `public static void main(String[] args)`: Entry point of the Java application. The program starts running from this method.
  - `Path goodFile`: Initializes a `Path` object for the file `StudentsGoodStanding.txt`.
  - `Path probFile`: Initializes a `Path` object for the file `StudentsAcademicProbation.txt`.

- **Comment:**
  - `// Write your code here`: Placeholder for developers to implement the functionality of the program.

This code serves as a template for managing students' standing records, either in good standing or academic probation, using file paths for organizing data.

**Step 1**: Create an application named `StudentsStanding.java` that allows you to enter student data consisting of an ID number, first name, last name, and grade point average. Have the program accept input until `ZZZ` is entered for the ID number. Depending on whether the student's grade point average is **at least 2.0**, output each record either to a file of students in good standing or those on academic probation.

**Step 2**: Create an application named `StudentsStanding2.java` that displays each record in the two files created in the `StudentsStanding` application. Display a heading to introduce the list produced from each file. For each record, display the ID number, first name, last name, grade point average, and the amount by which the grade point average exceeds or falls short of the 2.0 cutoff. For example, the output should be formatted as follows (note that the student info may vary):

**Probationary Standing**

- ID #10   Mike Green  GPA: 1.9    -0.10000000000000009 from 2.0 cutoff

**Good Standing**

- ID #100  Jill Green  GPA: 2.0    0.0 from 2.0 cutoff
- ID #50   Jane Doe    GPA: 3.7    1.7000000000000002 from 2.0 cutoff
