A Java program that creates a Bank Account with withdraw, deposit, and intrest functions. And a tester class, that tests the SavingsAccount class.

SavingsAccount.java

//SavingsAccount.java - Jimmy Kurian

public class SavingsAccount
{
	private double balance;
	private double interest;

	public SavingsAccount()
	{
		balance = 0;
		interest = 0;
	}

	public SavingsAccount(double initialBalance, double initialInterest)
	{
		balance = initialBalance;
		interest = initialInterest;
	}

	public void deposit(double amount)
	{
		balance = balance + amount;
	}

	public void withdraw(double amount)
	{
		balance = balance - amount;
	}

	public void addInterest()
	{
		balance = balance + balance * interest;
	}

	public double getBalance()
	{
		return balance;
	}

}

SavingsAccountTester.java

//SavingsAccountTester.java  - Jimmy Kurian

public class SavingsAccountTester
{
	public static void main(String[] args)
	{
		SavingsAccount jimmysSavings = new SavingsAccount(1000, 0.10);
		jimmysSavings.withdraw(250);
		jimmysSavings.deposit(400);
		jimmysSavings.addInterest();
		System.out.println(jimmysSavings.getBalance());
		System.out.println("Expected: 1265.0");
		//1000-250=750 => 750+400=1150 => 1150+1150*0.10=1265.0
	}
}

what are parts of the bank system?

how can we save our data by java programming?

why we have choosen private double balance;
private double amount;
why cannot we take public instead of private

@nandiniramana We took private for balance and interest because each account holder should have access only to their account and not to other's bank account. If we choose public , bank balance of an individual customer will be open to all the account holders.

is it possible to display this on a lcd screen?

how can i create multiple objects
please show me with an example

@arunandrews123 It is very easy to create multiple objects.Just use different object names.
Ex : SavingsAccount MySaving = new SavingsAccount(1000, 0.10);
SavingsAccount SamuelSavings = new SavingsAccount(1000, 0.10);
SavingsAccount DanielSavings = new SavingsAccount(1000, 0.10);

how we can make this program with user input

public SavingsAccount()
{
balance = 0;
interest = 0;
}

public SavingsAccount(double initialBalance, double initialInterest)
{
	balance = initialBalance;
	interest = initialInterest;
}

not complaining?

how we can make this program with user input

Using Scanner class

Java Program to Create Account with 1000 Rs Minimum Balance, Deposit Amount
Withdraw Amount and Also Throws LessBalanceException. It has a Class Called
LessBalanceException Which returns the Statement that Says WithDraw Amount(_Rs) is No
Valid. It has a Class Which Creates 2 Accounts, Both Account Deposite Money and One
