Question

Create an application in Java that asks a user for a number of hours, days, weeks, and years. It then computes the equivalent number of minutes (ignoring leap years).

Answer 1

Answer:

//import the Scanner class

import java.util.Scanner;

//Begin class definition

public class NumberOfMinutes{

    //Begin main method

    public static void main(String []args){

   

       //Create an object of the Scanner class

       Scanner input = new Scanner(System.in);

       

       //initialize a variable nm to hold the number of minutes

       int nm = 0;

       

       //Prompt the use to enter the number of hours

       System.out.println("Please enter the number of hours");

       

       //Receive the input using the Scanner object and

       //Store the entered number of hours in a variable nh

       int nh = input.nextInt();

       

       //Prompt the user to enter the number of days

       System.out.println("Please enter the number of days");

       

       //Receive the input using the Scanner object and

       //Store the entered number of days in a variable nd

       int nd = input.nextInt();

       

       //Prompt the user to enter the number of weeks

       System.out.println("Please enter the number of weeks");

       

       //Receive the input using the Scanner object and

       //Store the entered number of weeks in variable nw

       int nw = input.nextInt();

       

       //Prompt the user to enter the number of years

       System.out.println("Please enter the number of years");

       

       //Receive the input using the Scanner object and

       //Store the entered number of years in a variable ny

       int ny = input.nextInt();

       

       //Convert number of hours to minutes and

       //add the result to the nm variable

       nm += nh * 60;

       

       //Convert number of days to minutes and

       //add the result to the nm variable

       nm += nd * 24 * 60;

       

       //Convert number of weeks to minutes and

       //add the result to the nm variable

       nm += nw * 7 * 24 * 60;

       

       //Convert number of years to minutes and

       //add the result to the nm variable

       nm += ny * 52 * 7 * 24 * 60;

       

       //Display the number of minutes which is stored in nm

       System.out.println("The number of minutes is " + nm);

    }   //End main method

}  //End of class definition

Sample Output:

Please enter the number of hours

>>12

Please enter the number of days

>>2

Please enter the number of weeks

>>4

Please enter the number of years

>>5

The number of minutes is 2664720
