I'm using Eclipse and even though I've done more challenging things than this I keep getting stuck no matter how hard I hammer away at it.

This is a package, so the end of the first part (Driver Class?) is really what I'm having trouble with. Comments are included in the code. Also including the second part/ class is included.

Any guidance, help, flashing light bulbs would be greatly appreciated.

package 6;

import java.util.Scanner;
import java.text.DecimalFormat;



/**
 * @author Me
 *

 */


public class testAccount {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		String input;
		double balance = 0, InterestRate = 0;
		double interest, deposit, withdrawals;
		double totalInterest=0, totalDeposits=0, totalWithdrawals=0;
		int month=0;
		char repeat='Y';
		
	    Scanner keyboard = new Scanner(System.in);

		DecimalFormat degrees = new DecimalFormat("#,###.00"); 
		
		System.out.println("What is your account's starting balance?");
	    balance= keyboard.nextDouble();
		
		
		
	     System.out.println("What is your annual interest rate?");
		 InterestRate= keyboard.nextDouble();
		
		
		SavingsAccount account= new SavingsAccount (balance, InterestRate);
		interest=account.MonthlyInterestRate(InterestRate);
		balance=account.calculateInterest(balance);
		//me testing to see If I can at least get the right balance but
		///Something is wrong with my decimal formatter, 
	    //keeps adding two 00's when I tested it
	     System.out.println("Your balance is is" +degrees.format(balance));

	   //How do I step into this Loop?

		while ( repeat =='Y'|| repeat =='y');
		{
			month++;
			System.out.println("What are your deposits?");
			deposit=keyboard.nextDouble();
		     account.deposit(deposit);
		     System.out.println( "your deposits" +deposit);
		     System.out.println("balance" +balance);
			System.out.println("What are your withdrawals?");
			withdrawals=keyboard.nextDouble();
		     account.withdraw(withdrawals);
			//Around here I'm supposed to be using the Accumulators to set keep count of
		     //totalwithdrawals,totaldeposits etc.
			
			System.out.println("Calculate Month" + (month +1) + "Y/N .");
			repeat=keyboard.nextLine().charAt(0);
		}
	
		System.exit(0);
	}

}

and this is what it links to
I'm pretty sure (92% at least)most of it is correct

Hope these points helps you

1] There is nothing wrong with the formatter. It is only formatting the output for the value in 'balance'. Check whether the formula for calculating balance is correct or not

2] For the part

//How do I step into this Loop?
 
while ( repeat =='Y'|| repeat =='y');

remove the semicolon. Be careful with semicolons for loops and conditional statements

for the part

//How do I step into this Loop?
 
while ( repeat =='Y'|| repeat =='y');

i believe that using

while ( repeat.equalsCaseInsensitive("Y")) {

}

will enable you to enter the loop... iirc, you need to use .equals() to compare two strings, not the == operator.

TJ

Actually 'repeat' is of type char hence

while ( repeat.equalsCaseInsensitive("Y")) {
 
}

wont work in this case

You are processing the input with the account object, which is defined as a SavingsAccount class. The subclass containing the deposit and withdrawal methods is named as Bank Account! Perhaps when you decided to rename one you should have renamed both!
To accumulate the totals you seem only to need

totalDeposits+=deposit;

and for totalwithdrawals.

Design and implement a small system in Java for representing different geometrical shapes.

Your system should be able to handle the following shapes: triangle, rectangle, square, and circle.

Each shape has a name and colour, as well as appropriate dimensions.

An example of dimensions you can use to describe a shape is:

• Triangle – the lengths of the three sides
• Rectangle – width and height
• Square – width of the side
• Circle – radius

Each shape also has an area. Your program should be able to display details for each shape on the screen.

Your program should demonstrate the use of aggregation, polymorphism and inheritance where appropriate.

Write a menu-driven system that will allow you to display details of a bag of shapes and to modify them. Initially you should create several random shapes. Your system should offer options to select which shape you want to modify and should allow you to input new values for the attributes you wish to change.


DELIVERABLES

You should submit the Java code (source code and classes) for your program, as well as a short documentation of your system.

The documentation should discuss and justify the decisions taken when designing the system – e.g. the attributes and methods included for each shape, clearly identifying (and motivating the need for) aggregation, polymorphism and inheritance where appropriate.

The documentation should also describe the behaviour of your system (the different options) and should include few sample dialogs.
This is a sample output of what your system should be able to do.
There is no need to recreate the exact output as the listed below.

Use code tags and don't give away answers.

This forum is not for doing other's people homework. The rest of us didn't give the solution for a reason. We are not here to do it for them.

Ok you know the answer. So what? With your post you are implying that you are the smart one who posted the solution to a 1 month-old thread, which I find insulting for the rest,
And we are the stupid for not wanting to do someone else's homework so he can get all the credit without trying.
