I want from the java to reads all numbers from the user as long as the number entered by user is bigger than the previous number. But i could write it for only positive numbers. How i can fix code below if all numbers included. If it is possible please write the solution for beginners because its my first year in computer science in college and I haven't learn a lot yet.

import acm.program.*;

public class IncreasingOrder extends ConsoleProgram {

public void run() {

    int previousNumber = 0;

    int total = 0;

    int count = 0;

    while(true) {
        int n = readInt("Enter > ");
        if (n <= previousNumber) break;

        total += n;
        count++;
        previousNumber = n;
    }
    println("You have entered " + count + " numbers in increasing order.");
    println("Sum of these " + count + " numbers is " + total + ".");        
}

}
