Currency Calculator Java Program Solution


Write a program to convert dollars into Indian money.

The currency calculator is capable of converting only USA, Canada, Singapore and Hong Kong dollars to INR.

Prompt the user to enter the Currency code and the amount to be converted. Display the result as given in the sample output.

Note the currency code and exchange rate for the countries

{Canada –CAD, 52.08} , {Hong Kong – HKD, 8.86}, {Singapore – SGD, 51.29} {USA – USD, 69.55}

Store these values as double and after calculation, print the values to two decimal places. Use System.out.printf to print correct to 2 decimal places.

        String country_name[]={"Canada", "Hong Kong", "Singapore", "USA"};
        double exg_rate[]={52.08, 8.86, 51.29, 69.55};
        int flag=0;
        Scanner sc= new Scanner(;
        System.out.println("Enter the currency code");
            String cur=sc.nextLine().toUpperCase();
          for(int i=0;i<=3;i++)
                    System.out.println("Enter the amount");
                    int amt=sc.nextInt();
                    double ans=amt*exg_rate[i];
                    DecimalFormat f= new DecimalFormat("########0.00");
                    System.out.println(country_name[i]+" dollar "+amt+" equals to "+f.format(ans)+" Indian Rupee");
                System.out.println("Currency code not found");
