illegal start of expression

[wardduncan]

I need some help with understanding an error that I am getting. Can anyone help me. Here is my problem. I am trying to hardcode information for a mortgage calc and I am getting an illegal start of expression error. Here is an example:

MortgageLoanCalculator.java:15: illegal start of expression
double interestRate = 5.7%; // Interest Rate = 5.75%

What does it mean?

Can you post the previous few lines of the code ... the problem could be in the previous lines too ... look at them.

[wardduncan]

Sure. Here is the program.

public class MortgageLoanCalculator
{
    //Main method
        public static void main(String [] args)
    {
        double interestRate = 5.7%;                     int numberOfYears = 30;                      
                 double loanAmount = %200,00;                   

    //Enter monthly interest rate
    System.out.println("The interest rate is:" + interestRate);
    System.out.println("The loan amount is:"  + loanAmount);
    System.out.println("The term in years is:" + numberOfYears);

    }
}

The % is a sign for modular division in java.

[server_crash]

you might want to play around with the DecimalFormat class some, if you want your numbers to have commas after every three numbers and an % before or after your numbers.

Try this out now

public class MortgageLoanCalculator
{
//Main method
public static void main(String [] args)
{
double interestRate = 5.7; // you are defining a double value .. and % is not a double.
int numberOfYears = 30;
double loanAmount = 20000; //java doesnt recognize comas in doubles.

//Enter monthly interest rate
System.out.println("The interest rate is:" + interestRate);
System.out.println("The loan amount is:" + loanAmount);
System.out.println("The term in years is:" + numberOfYears);

}
}
