    Default Can't declare Variable in new method

    In the very last method below
    import javax.swing.JOptionPane;
    public class program08 {
    public static void main(String[] args) {
        String getWeightString = JOptionPane.showInputDialog(null,
                "Enter the weight of the package");
        double getWeight = Double.parseDouble(getWeightString);
     
        String handling = JOptionPane.showInputDialog(null,
               "Would you like Special handling? Enter 'Y' for yes.");
        char handlingChar = handling.charAt(0);
     
        String insurance = JOptionPane.showInputDialog (null,
                "Would you like insurance? Enter 'Y' for yes.");
        char insuranceChar = insurance.charAt(0);
     
     
     
     
        JOptionPane.showMessageDialog(null, "The total cost is" + "");
        }
     
    public static double price(double getWeight) {
        double price;
        if (getWeight <= 2.00)
            price = 1.00;
        else if (getWeight > 2.00 && getWeight < 5.00)
            price = 2.00;
        else
            price = 4.00;
     
        return price;
        }
     
    public static double handlingPrice(char handlingChar) {
        double handlingPrice =0;
        if (handlingChar == 'Y' || handlingChar == 'y')
            handlingPrice = 5.00;
     
        return handlingPrice;
        }
     
    public static double insPrice(char insuranceChar) {
        double insPrice = 0;
        if (insuranceChar == 'Y' || insuranceChar == 'y')
            String insPriceString = JOptionPane.showInputDialog(null,
                    "How much insurance would you like?");
        insPrice = Double.parseDouble(insPriceString);
        insPrice += insPrice * 0.10;
        return insPrice;
        }
     
     
    }

    At the line that reads "String insPriceString = JOptionPane.showInputDialog"
    I get a warning that reads "Variable declaration not allowed here"
    The assignment requires that the variable for the amount of insurance the user wants, if they want insurance, to be declared in a different method, not the main method.

    You need to add {}s to enclose the statements controlled by the if statement.
    If you don't understand my answer, don't ignore it, ask a question.

    The if statement is not a loop. In only needs {} if it is a loop, no?

    you have to add braces in your condition

    and concentrate with your return statement..

    Learn this: coding style - Single statement if block - braces or no? - Programmers

    You should always code {}s with if, else and loops
