Polimorfismo – Exemplo pratico

Ola pessoal, criei duas video aulas, parte 1 e 2 sobre polimorfismo. Na minha opiniao, ficaram bem explicativas. Mas caso surgir duvidas, coloquem a duvida aqui.

Bom pessoal, como exercicio para voces eu deixo tirar alguns erros tipo:

Apenas somar, subtrair, dividir ou multiplificar se os dois campos nao estiverem vazios e se eles tiveram apenas numero.

Como criar uma janela usando JFrame

Bom pessoal, o codigo que postarei aqui eu retirei do livro Introduction to GUI with Java Swing, que comecei a ler.

Esta é primeira aplicaçao que colocarei aqui entre muitas outras que colocarei ao decorrer da leitura.

Ela é bem simples, a função dela é apenas mostrar uma janela simples na tela, sem componente nenhum.

Fiz uma pequena modificação para funcionar sem precisar criar o pacote, visto que ele estava dentro de um, package its.SimpleFrame;.

Segue o codigo:

import javax.swing.JFrame;

public class SimpleFrame extends JFrame
{
  public SimpleFrame()
  {
    this.setSize(200,200);
    this.setLocation(200,200);
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }

  //Makes the frame visible
  public void showIt() {
    this.setVisible(true);
  }

  //Makes the frame visible and sets the title text.
  public void showIt(String title){
        this.setTitle(title);
	this.setVisible(true);
  }

  //Makes the frame visible and sets the title text
  //and the position of the window

  public void showIt(String title,int x,int y){
    this.setTitle(title);
	this.setLocation(x,y);
	this.setVisible(true);
  }

  //Makes the frame invisible
  public void hideIt(){
    this.setVisible(false);
  }
}

O codigo acima é apenas um, vamos dizer assim, montador da janela. Atravez da proxima aplicação é que é executado o codigo acima.

public class SimpleFrameDriver
{
  public static void main(String[] args)
  {
        SimpleFrame sFrame1 = new SimpleFrame();
	SimpleFrame sFrame2 = new SimpleFrame();
	sFrame1.showIt("SimpleFrame 1");
	sFrame2.showIt("SimpleFrame 2",300,300);
  }
}

Bem, o que ele faz é bem simples. Ele cria varios metodos sobrecarregados. Isto quer dizer, metodo com nomes iguais porem que recebem argumentos diferentes.

        SimpleFrame sFrame1 = new SimpleFrame();
	SimpleFrame sFrame2 = new SimpleFrame();

Nesta duas linhas ele cria os objetos sFrame1 e sFrame2.

	sFrame1.showIt("SimpleFrame 1");
	sFrame2.showIt("SimpleFrame 2",300,300);

Nestas duas linhas ele chama os seguintes metodos showIt:

Código:

  public void showIt(String title){
    this.setTitle(title);
	this.setVisible(true);
  }

  public void showIt(String title,int x,int y){
    this.setTitle(title);
	this.setLocation(x,y);
	this.setVisible(true);
  }

Apesar do nome e do modificador de acesso e o retorno serem identicos, o parametro é diferente. Isso é diferente para o JVM, para ele, estes metodos nao sao iguais. O metodo hideIt() ele colocou no codigo apenas para falar ( no livro esta falando ) que se voce executar este metodo, o programa ainda continuara rodando. Ou seja, vamos dizer que voce tivesse um botao e ao clicar ele chamasse este metodo. O que iria acontecer é que o JFrame ficaria invisivel, mas nao fecharia. Se por acasso voce abrisse outro programa e fechasse novamente do mesmo modo, abrisse outro.. e assim por diante.. isto consumiria muita memoria. Para fechar um JFrame, tem que ser atravez do atributo setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);. Nao irei mostrar, apenas mencionar. No curso do neri vi que tem outros tipos de constantes estaticas (final static… Orientação a Objetos hein pessoal) igual a esta. Vamos dizer que seu programa tivesse um botao que abriria um novo JFrame. Se voce coloca o setDefault.. Isto fecharia todo o programa. Por isto, existe a constante DISPOSE_ON_CLOSE. Se por acaso alguem quiser ver um uso disso tudo que falei e nao mostrei, peça. Nao irei fazer o tutorial se nao tiver certeza que alguem ira ler ne… Bom, abaixo segue uma imagem da execução do codigo mostrado acima.

Qualquer duvida sobre o codigo aqui descrito, pergunte! Nao fique com medo de perguntar.

Espero que voces tenham gostado e ate a proxima.

Rosetta Stone – English (American) Level 1, 2, 3

Rosetta Stone software is built around a concept called Dynamic Immersion, an unique learning method that uses a computer to mimic the ways in which you learnt your first language.
This approach is simple, but incredibly effective as it allows your brain to adapt quickly as your knowledge grows.

Our language courses are highly interactive and visually engaging and we’ll never ask you to translate back into your native language or memorise vocabulary lists. Instead you’ll learn through a complete immersion process. Relate what you see and hear to familiar, real-life images and situations. Practise and perfect your pronunciation against native speakers using our innovative voice recognition technology and receive immediate feedback to help consolidate and reinforce your learning.

You�ll experience continuous progress and regular breakthroughs because our Adaptive Recall technology remembers language you find difficult initially and reintroduces it at optimal intervals during the course; helping you understand and retain language for use in the real world.

Instructions:

1. Burn or mount the Application ISO using one of the many ISO utilities. (e.g PowerISO to mount )
2. Turn off all Anti Virus applications.
3. Install Rosetta Stone 3.3.5
4. DO NOT let the application run at the end of the install.
5. Copy the “RosettaStoneVersion3.exe” file from the “Crack” folder, and overwrite the original one in the directory where you installed “Rosetta Stone 3.3.5.exe”.
(Default installation directory: C:\Program Files\Rosetta Stone\)
6. Run the “Rosetta Stone 3.3.5 Product Activation Patch – JDS.exe” file from the “Crack” folder.
7. Done
8- Note: You will see a prompt everytime you start Rosetta Stone 3.3.5 that says: There was a minor error.
This is normal, just click “OK” to continue. You don’t need to crack Rosetta Stone 3.3.5 again
when you update a language file.
9. Burn or mount one of the language ISO files
10. Run the Rosetta Stone Application
11. The application will ask to install a language
12. It should search and find the language disk or mounted ISO
12. Continue for all languages and levels you want to install.
