INTRODUCTION

TEMPERATERE CONVERTER

Change the temperature from one form to other.

Celcius Fahrenheit Reaumur

This program provide a different form of temperature

- Celcius: it is SI unit of temperature.

- Fahrenheit: On the Fahrenheit scale, the freezing point of water is 32 degrees Fahrenheit (F) and

the boiling point 212 F (at standard atmospheric pressure). This puts the boiling and freezing points of

water exactly 180 degrees apart.

- Reaumur:The Raumur scale (R, Re, R), also known as the "octogesimal division" isa temperature scale in which the freezing and boiling points of water are set to 0 and 80 degrees respec-

tively. The scale is named after Ren Antoine Ferchault de Raumur who first proposed something simi-

lar in 1730.

ABOUT JAVA

Java technology is both a programming language and a platform.

The Java Programming Language

The Java programming language is a high-level language that can be characterized by all of the

following buzzwords:

Compiled and Interpreted

Platform independent & Portable

Object-Oriented

Robust & Secure

Distributed

Simple , Small & Familiar

Multithreaded & Interactive

High Performance

Dynamic & Extensible

The Java Environment

Program Organization Standards

Each class is implemented in its own source file.

Include one class per file:Name of the Java file is the same as the class name.

Java applications must include a class with a

main method.E.g.,

public static void main(String args[])Unlike C++ a logic expression does not evaluate to 0 (FALSE) and non-0 (TRUE), it evaluates

to eithertrue orfalse

true, false are values of the boolean data Type.

Java Exception Handling

An exception is an object that defines an unusual or erroneous situation.

An exception is thrownby a program or a runtime environment and can be caughtand handled

appropriately.

Java supports user-defined and predefined exceptions:

ArithmeticException ArrayIndexOutOfBoundsE xception


3/10

FileNotFoundException

InstantiationException

Exception handling allows a programmer to divide a program into a normal executionflow and

an exception execution flow.

If an exception is not handled the program will terminate (abnormally) and produce a message.

public class DivideBy0

{public static void main (String[] args) {

System.out.println(10/0);

}}

Java.lang.ArithmeticException: / by zero

at DivdeBy0.main(DivdeBy0:3)

try {

statement-list1} catch (exception-class1 variable1) {

statement-list2} catch (exception-class2 variable2) {

statement-list3

} catch

The Java Platform

Aplatform is the hardware or software environment in which a program runs. We've alreadymentioned some of the most popular platforms like Microsoft Windows, Linux, Solaris OS, and

Mac OS. Most platforms can be described as a combination of the operating system and underly-

ing hardware. The Java platform differs from most other platforms in that it's a software-only

platform that runs on top of other hardware-based platforms.The Java platform has two components:

TheJava Virtual Machine TheJava Application Programming Interface (API)

The general-purpose, high-level Java programming language is a powerful software platform.Every full implementation of the Java platform gives you the following features:

Development Tools: The development tools provide everything you'll need for compiling, run-

ning, monitoring, debugging, and documenting your applications.

Application Programming Interface (API): The API provides the core functionality of the Ja-va programming language. It offers a wide array of useful classes ready for use in your own ap-

plications. It spans everything from basic objects, to networking and security, to XML generation

and database access, and more.

Deployment Technologies: The JDK software provides standard mechanisms such as the Java

Web Start software and Java Plug-In software for deploying your applications to end users.

Program Organization

In the Java programming language, all source code is first written in plain text files ending with

the .java extension. Those source files are then compiled into .class files by the javac compiler. A.class file does not contain code that is native to your processor; it instead contains bytecodes

the machine language of the Java Virtual Machine1 (Java VM). The java launcher tool then runs

your application with an instance of the Java Virtual Machine.

Swing

The Java Swing provides the multiple platform independent APIs interfaces for interacting be-tween the users and GUIs components. All Java Swing classes imports form the import ja-

vax.swing.*; package. Java provides an interactive features for design the GUIs toolkit or com-

ponents like: labels, buttons, text boxes, checkboxes, combo boxes, panels and sliders etc. All

AWT flexible components can be handled by the Java Swing. The Java Swing supports the plug-ging between the look and feel features. The look and feel that means the dramatically changing

in the component like JFrame, JWindow, JDialog etc. for viewing it into the several types of

window.

1. JOptionPane Basics

Static methods in the JOptionPane class let you easily create modal dialogs to show messages

(JOptionPane.showMessageDialog), to ask for confirmation (JOptionPane.showConfirmDialog),to let the user enter text or to choose among predefined options (JOptionPane.showInputDialog),

or to choose among a variety of buttons (JOptionPane.showOptionDialog). Each of these meth-

ods either returns an int specifying which button was pressed, or a String specifying the option

selected.
