Format the output

[moustafa taha]

hello every one
this program compares loans with various interest rates

public static void main(String[] args) {
        Scanner input=new Scanner(System.in);
        //Prompt the user to enter the loan amount
        System.out.print("Enter the loan amount:");
        int loanAmount=input.nextInt();
        //Promp the user to enter the period in number of years
        System.out.print("Enter number of years:");
        int numberOfYears=input.nextInt();
        System.out.println("Interest Rate   Monthly Payment   Total Payment");
        int months=numberOfYears*12;
        double interestRate=5;
        double monthlyPayment;
        double rate;
        double totalPayments;
        while(interestRate<=8)
        {
            rate=interestRate/1200;
            //Calculating monthly payment
             monthlyPayment=(rate+(rate/((Math.pow((1+rate),months))-1)))*loanAmount;
            //Calculating total payments
             totalPayments=monthlyPayment*months;
            System.out.printf("%-13f   %-15.2f   %-13.2f\n",interestRate,monthlyPayment,totalPayments);
            interestRate+=(double)1/8;
        }
    }

}

I've used here the printf method in this line

System.out.printf("%-13f   %-15.2f   %-13.2f\n",interestRate,monthlyPayment,totalPayments);

the problem in the format of this first column of the output
5.000000
5.125000
5.250000
5.375000
5.500000
5.625000
5.750000
5.875000
6.000000
6.125000
6.250000
6.375000
6.500000
6.625000
6.750000
7.000000
7.125000
7.250000
7.375000
7.625000
7.750000
7.875000
8.000000
i want to remove zeros and make the format like this
5%
5.125%
5.25%
....
....
8.0%
thanks

You can solve your problem using the format method and restrict your decimal places upto which digit you want.
For eg:
To restrict to 3 digits use

String s=String.format("%.3f",4765.098000);
System.out.println(s);

It will give output
4765.098
i.e upto 3 decimal places.
