Java's rich Swing api provides many features for creating GUI interface Swing components run on the event dispatch/queue thread.. This means even after the main thread has finish running..u still have ur gui displaying. It also means when an Exception occurs in most cases your GUI interface remains but may not work accordingly well Most java textbooks begin introduction to swing by with the JOptionPane component The JOptionPane provides java programmer's with an input dialog as well as a message dialog box.. So for those who are still used to command line programs you can kick start a more visual approach as java has wealthy options available Visit the java extension packages for various swing components javax.swing.*; Using the java SE documentation you can learn to use this Api's as they were designed The JOptionPane class has static methods for message and input dialogs JOptionPane.showMessageDialog("your message" gives you a dialog box that prints the string parameter passed to it String name=JOptionPane.showInputDialog("what is your name" gives you a dialog box that receives input and returns a string to your program.. |

Re: Java Tutorial For Beginners by nnasino(m): 6:53pm On Jun 04, 2015 |
MUKU5262:Make sure the class name is actually best as Java is case sensitive and thus will not find the class is it is named something else. Also make sure that there is a main method in the best class. If your problem isn't solved then please show us the source code. Cheers |

HOJOSKID: I don't know if you have gotten an answer for this but let me say a few things anyway. 1. When learning any programming language, it is best to study the conventions so that as you learn, you begin to learn the "Good Practices" along. Let's start from the name of your class : By convention, Java uses CamelCase for class names. Which means that the name of your class should have been something like VariableDeclaration 2. Under no circumstances should you put variables in the body of the class, they should go into method bodies. The only variables allowed to stay in class body are instance variableswhich are always preceded by access modifiers private, protected or public In other words, I am saying remove these
and move them to the method body. - Verem Dugeri |

Converting a data type to another one is called casting. I suggest to take a look at this casting in java course to understand better the concept. |
