WebDriver PageFactory.initElements [Why we need]

GooglePage.java

 public class GooglePage extends MyDriver{    
      @FindBy(how = How.NAME, using = "q")  
       private WebElement searchtext;  
      public GooglePage() {  
             super();
             System.out.println("cool stuff!");  
      }  
       public void typeText(){  
           searchtext.sendKeys("abc"); 
      }  
 } 

Testcode:

public class TestCode{

public TestCode(){

GooglePage googlePage = PageFactory.initElements(driver, GooglePage.class); 

//We need to use PageFactory.initElements(driver, GooglePage.class) 

// instead of "new GooglePage() since the GooglePage defines the WebElement using @FindBy. 

          } 

    public void testCase1(){

   googlePage.typeText();

   .... 

  }

}
