Help with constructor in java

[mathias]

Hi, I've a question about this code:

Code:

public class Test {

  public Test(){}
  
  public static void main(String args[]) 
  {
    System.out.println(new Test().i);
  }

  int i;
}

The Java book I'm consulting says that when you provide a parameter less constructor, you replace the Java-provided default constructor. It also states that the Java-provided default constructor initialises all attributes to a default value for example zero for an integer.

However, if the above code is really replacing the default constructor, then how is int i being set to zero?

I suppose in a way this seems a weird question, it's just I'm trying to get a good understanding of the basics.

Thanks.

When you declare it it's set to zero. It doesn't really have anything to do with the constructor.
