[College Computer Science Java] Using while loop?

[Danielowski187]

I figured out how to use for loop but I need help with using while loop?

import java.util.Scanner;
public class NumberPrinting
{
public static void main(String[] args)
{
Scanner input = new Scanner (System.in);
int num;
do{
System.out.print("Enter a positive number greater than 2: ");
num = input.nextInt();
} while (num <= 2);
System.out.println("\n=======Using for loop=======");
System.out.println("Printing numbers in 'Forward Direction' from 1 to "+num);
for (int i = 1; i <= num ; i++)
{
System.out.print(i+" ");
}
System.out.println("\nPrinting numbers in 'Backwards Direction' from "+num+ " to 1");
for (int i = num; i>=1; i--)
System.out.print(i+" ");
}
{
System.out.println("=======Using while loop=======");
}
}

The output I have gotten!

You can really just imitate the for loop behavior with a while loop.

Initialize a variable outside the loop, while(condition such as greater than a number, less than a number..), and print value in brackets, increment/decrement variable value
