Command-line arguments determining ascending or descending order.

Hello,

I'm in the process of writing a .java program that reads in 3 integer command-line arguments (we'll call them a, b, c).

The purpose of this program is to determine (by using a boolean declaration) whether or not the three values passed are in strictly ascending/descending order.

e.g.

% java Test 49 17 10
true

% java Test 10 49 17
false

The portion that is a little puzzling is how to use an "if else" statement to detect if the values are in ascending/descending order.

Here's what I have, please critique my code so I can improve! Thanks.

public class Ordered {

	public static void main (String[] args) {
	
	int firstNum = Integer.parseInt(args[0]);
	int secondNum = Integer.parseInt(args[1]);
	int thirdNum = Integer.parseInt(args[2]);

	boolean isOrdered;
	
		if (values are ascending or descending) {
			isOrdered = true;
			System.out.println(isOrdered)
		
	    }	
		else {
			isOrdered = false;
			System.out.println(isOrdered)
	}
	
}
