ABSTRACT In finance,an exchange rate between two
currencies is the rate at which one currency will be exchanged for another.
It is a useful tool which gives us the value of certain amount of one currency to be converted in to a different currency.
It is also regarded as the value of one country’s currency in terms of another currency.
In this project we are going to display a web window in which currency options are given and the conversion value is displayed in the next window.

INTRODUCTION Currency converter is a tool used to convert
one country’s currency to another. In this project by the knowledge of usage of
currency converter a program is designed in java language.
In this Currency Converter application, it is going to display a web page where u can choose to display the converter or the exchange rate of one currency with all other currencies in the form of table. In the converter u are given a choice to choose two currency names from the list of currency names displayed.
ALGORITHM Step1: Start Step2: Enter the amount value Step3: Select the currency from and to Step4: Click on the convert button Step5: The value will be displayed Step6: Exit

Input given is amount value and currency names are
selected from the options
Click on convert
Given amount value isOutput value
will be positive
Output value will be
negative
Output will be zero

DESIGNING
We are using different concepts like HTML for creating web page SERVLETS for creating dynamic pages and for displaying output JDBC for establishing the connection
with the database. This code is implemented by using TOMCAT
server.

CONCLUSION
Therefore , currency converter is developed and is used for knowing the currency’s value.
It can be further developed by including more currency options, and by shown currency value tables for the user.
