Question

Write in java

Q 4.Centigrade and Fahrenheit are two scales to measure temperature. Write a program that that prompts the user to enter Centigrate and then print the Fahrenheit.

Use following formula for conversion.

Fahrenheit = Centigrade*1.8 +   32 ;

Q. 7 Write a program to calculate the bill of a customer. The program will

-           Prompt the employee to enter the monthly plan fees.

-           Prompt the employee to enter the rate per additional minute.

-          Print the bill

The bill will be calculated as follows: if the number of consumed minutes is 300 minutes or less, the client pays only his regular monthly fees. If the number of minutes is more than 300, then he should pay in addition to the regular monthly fees, an extra amount for each additional minute consumed (over the allowed 300 minutes using rate per additional minute.).

Answer 1

Q4.

import java.util.Scanner;
public class Main
{
   public static void main(String[] args) {
       System.out.println("Enter Temperature in Centigrade"); //promt user to write temp in centigrade
       double Centigrade;
       double Fahrenheit;
       Scanner s= new Scanner(System.in);
   Centigrade = s.nextDouble();
   Fahrenheit = Centigrade*1.8 + 32 ;
   System.out.println("Temperature in Fahrenheit"+Fahrenheit); //print temperature in fahrenheit
   }
}

Q7.import java.util.Scanner;
public class Main
{
   public static void main(String[] args) {
   Scanner s= new Scanner(System.in);
       System.out.println("Enter Monthly plan fees"); //Promt employee to enter monthly plan
       int mf=s.nextInt();
       System.out.println("Rate per additional minute"); //Prompt employee to write rate per extra min
       int rpam=s.nextInt();
       System.out.println("No of Minutes Consumed"); //Promt employee to write consumed time
       int nmc=s.nextInt();
       int money;
       if(nmc>300)
       { int a=nmc-300;
       money=mf+ a*rpam;
       System.out.println("Please pay Rs. "+money); //Print the bill
       }
       else
       { money=mf;
       System.out.println("Please pay Rs. "+money); //Print the bill
       }
