Question

Write a java program that asks the user to enter an integer. The program should then print all squares less than the number entered by the user. For example, if the user enters 120, the program should display 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.

Answer 1

import java.util.Scanner;

public class Squares {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter a positive integer: ");
        int n = in.nextInt();
        for (int i = 0; i * i < n; i++) {
            System.out.println(i * i);
        }
    }
}

Enter a positive integer: 120 100
