    Lightbulb Different approach to this code

    Instructor informed me today that my code is similar to another students and I must redo it. I am not quite sure what to change to give her what she is asking for. Any suggestions? new to JAVA.

    <import java.util.*;
    import java.io.*;
    import java.text.SimpleDateFormat;
     
    public class A2RE5161843 {
     
        public static void main(String[] args) throws IOException {
            Scanner input = new Scanner(System.in);
            int firstNum = 0, secondNum = 0;
            boolean valid = false;
            while (!valid) {
                System.out.print("Enter first number :");
                firstNum = input.nextInt();
                if (firstNum < 0) {
                    System.out.println("Enter positive number ");
                } else if (firstNum > 1000) {
                    System.out.println("Enter number less than 1000");
                } else {
                    valid = true;
                }
            }
            valid = false;
            while (!valid) {
                System.out.print("Enter second number :");
                secondNum = input.nextInt();
                if (secondNum < 0) {
                    System.out.println("Enter positive number ");
                } else if (secondNum > 1000) {
                    System.out.println("Enter number less than 1000");
                } else if ((secondNum - firstNum) < 10) {
                    System.out.println("Second number should be at least 10 greater than first number");
                } else {
                    valid = true;
                }
            }
            FileWriter fw = new FileWriter(new File("A2RE5161843.txt"));
            //Use a for loop to perform the following steps:
            //Continue writing to the same file as before.
            //Write ad label as before.
            //Output all odd numbers between firstNum and secondNum inclusive, one number per line.
            fw.write("1. All odd numbers between firstNum and secondNum inclusive");
            fw.write(System.getProperty("line.separator"));
            for (int i = firstNum; i <= secondNum; i++) {
                if (i % 2 != 0) {
                    fw.write(i + "");
                    fw.write(System.getProperty("line.separator"));
                }
            }

            fw.write("2. The sum of all numbers between firstNum and secondNum exclusive");
            fw.write(System.getProperty("line.separator"));
            int sum = 0;
            for (int i = firstNum + 1; i < secondNum; i++) {
                sum += i;
            }
            fw.write(sum + "");
            fw.write(System.getProperty("line.separator"));
            //Output all numbers from secondNum to firstNum in a single line with commas separating the numbers.
            fw.write("3. All numbers from secondNum to firstNum in a single line with commas separating the numbers");
            fw.write(System.getProperty("line.separator"));
            for (int i = firstNum; i <= secondNum; i++) {
                fw.write(i + ",");
            }
            fw.write(System.getProperty("line.separator"));
            //Write the date and time as the last line in the file in the format yyy-mm-dd hh:mm:ss.
            fw.write("4. The date and time as the last line in the file in the format yyy-mm-dd hh:mm:ss");
            fw.write(System.getProperty("line.separator"));
            fw.write((new SimpleDateFormat("yyyy-mm-dd hh:mm:ss")).format(new Date()));
            System.out.println("File Assignment2.txt written");
            fw.close();
        }

    Please edit your post and wrap your code with
    [code=java]
    <YOUR CODE HERE>
    [/code]
    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.
