Answer:

import java.util.Scanner;

public class ANot {

   public static void main(String[] args) {

Scanner input = new Scanner(System.in);

       System.out.println("Please Enter the number of fuel gallons in the car's tank: ");

       int numGallons = input.nextInt();

       System.out.print("What is the fuel efficiency of your car in miles/gallon ");

       double fuelEffi = input.nextDouble();

       System.out.print("How much is the price per gallon: ");

       double price = input.nextDouble();

       double milesCanGo = fuelEffi*numGallons;

       double numOfGallons100Miles = 100/fuelEffi;

       System.out.println("The cost per 100 miles is "+numOfGallons100Miles*price);

       System.out.println("Your car can go as far as "+milesCanGo+" miles with the current fuel " +

               "in your tank");

   }

}

Explanation:

Using Java programming language;

  1. Import the Scanner class to receive user input
  2. Prompt user to input numofGallons, fuelEfficiency and pricePerGallon
  3. Calculate the miles the car can go with the formula milesCanGo = numofGallons X fuelEfficiency
  4. Calculate the number of gallons for 100 miles distance (100/fuelEfficiency)
  5. The cost of driving 100 miles is (100/fuelEfficiency)*pricePerGallon
  6. Output cost for 100 miles and how far the car can go.

Write a program that asks the user to enter the amount s/he has budgeted for a month. The amount should be between 1000 and 2000
Elena-2011 [213]

Answer:

The program to this question can be given as:

Program:

  //import package for user input.

import java.util.*;      

//define class

public class Budget                      

{

public static void main(String [] a)            //define main method.

{

//creating Scanner class object.

Scanner ob =new Scanner(System.in);    

//define variable.      

double budgetamount=0, amountspent=0 ,difference=0,total=0,num=0 ;        

int count = 0;                            

System.out.println("How much have you budgeted for the month? :");        //print message.

budgetamount=ob.nextDouble();                             //taking input

       while(budgetamount != 0)           //checkig number greater then 4 digite.

       {

           budgetamount= budgetamount/10;        

           ++count;

       }

       if(count>4)                 //condition

       {

       System.out.println("enter each expense, then type -999 to quit: ");

       while(num!=-999)               //taking expense  

       {

       total=total+num;                 //totaling expense

       num=scan.nextDouble();                  

       }

       if(total<=budgetamount)           //condtion for over budget.

       {

       System.out.print("under budget:");         //print message

       System.out.print(budgetamount-total);

       }

       else

       {

       System.out.print("over budget:");              //for under budget

       System.out.print(total-budgetamount);

       }

       }

       else

       {

       System.out.println("not valid");        //message for number lessthen 4 digit.    

       }                                      

}

}

output:

How much have you budgeted for the month? : 1200.55.

enter each expense, then type -999 to quit: 365.89

556.90

339.98

-999

over budget:1262.77

Explanation:

The explanation of this program can be given as:

In the above program we import the package in that is used for scanner class. This class is used for the input from the user after input we use the while loop and if-else statement. The while loop is the entry control loop It is used for input validation and if-else is used for the checking condition. Then we insert expense that is inserted by the user. Then we calculate under-budgeted and over-budgeted by conditional statement that is if-else. and at the last we print it.
