Import java.util.Scanner;
public class MinutesConversion {
private static Scanner inputDevice;
public static void main(String[] args) {
int minutes, hours;
float days; // float for decimal point
inputDevice = new Scanner(System.in);
System.out.println("Please enter minutes for conversion >> ");
minutes = inputDevice.nextInt();
hours = minutes / 60;

System.out.println(+ minutes + " minutes is " + hours + " hour(s) or" + days " days");
}
}
