Forward reference

[Sanyev Babu]

Can anyone explain to me why this code produces the output 0

 
public class AQuestion 
{ 
 private int i = giveMeJ(); 
 private int j = 10; 
 
 private int giveMeJ() 
 { 
  return j; 
 } 
 
 public static void main(String args[]) 
 { 
  System.out.println((new AQuestion()).i); 
 } 
} 
 

Where as this code produces a forward reference compilation error.

 
public class AQuestion 
{ 
 private int i = j; 
 private int j = 10; 
 public static void main(String args[]) 
 { 
      System.out.println((new AQuestion()).i); 
 }
}
 

Thanks
