    Default Could anyone please help me with this program? and I did below code, but I may miss something.

    Create class SavingsAccount. Use a static variable annualInterestRate to store the annual interest rate for all account holders. Each object of the class contains a private instance variable savingsBalance indicating the amount the saver currently has on deposit. Provide method calculateMonthlyInterest to calculate the monthly company interest by multiplying the savingsBalance by annualInterestRate divided by 12 this interest should be added to savingsBalance. Provide a static method modifyInterestRate that sets the annualInterestRate to a new value. Write a program to test class SavingsAccount. Instantiate two savingsAccount objects, saver1 and saver2, with balances of $2000.00 and $3000.00, respectively. Set annualInterestRate to 4%, then calculate the monthly interest and print the new balances for both savers. Then set the annualInterestRate to 5%, calculate the next month’s interest and print the new balances for both savers.

    **filename: SavingAccount.java**
    SavingAccount class
    public class SavingsAccount [
    public static double annualInterestRate;
    private double savingsBalance;
    public SavingsAccount() [
    annualInterestRate = 0.0;
    savingsBalance = 0.0;
    ]
    public SavingsAccount(double intRate, double savBal) [
    annualInterestRate = intRate;
    savingsBalance = savBal;
    ]
    public double calculateMonthlyInterest() [
    double intRate = (savingsBalance * annualInterestRate/12);
    savingsBalance = savingsBalance + intRate;
    return intRate;
    ]
    public static void modifyInterestRate(double newInteresRate) [
    annualInterestRate = newInteresRate;
    ]
    public void setSavingsBalance(double newBal) [
    savingsBalance = newBal;
    ]
    public double getSavingsBalance() [
    return savingsBalance;
    ]
    public double getAnnualInterestRate() [
    ** return annualInterestRate;**

    Do you have any java programming questions?

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
    If you don't understand my answer, don't ignore it, ask a question.

    where did I miss.
    Why do you think something is missing?

    Please edit your post and wrap your code with code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.

    Code with code tags should look like this:
       int var = val;
       if(var > 2) {
          // do something
       }
    If you don't understand my answer, don't ignore it, ask a question.

    Sorry, we do not do students' assignments here.
    You need to explain what the problem is and post any error messages.

    AND you need to edit your post and wrap the code in code tags:

    [code]
    **YOUR CODE GOES HERE**
    [/code]

    to get highlighting and preserve formatting.
