New to Java

Hi,

Please see the code below. If at *** variable "i" is not set to 4, the output will be 3, if it is set, it'll be 4.
My question is... well, I don't know exactly, there could be many. This whole thing is strange for me.
(For example it seems that the constructor for the super class runs when i access an instance variable from it.)
Could somebody explain this topic or maybe help me with directing to an article?

public class TryThis {
    
    public static void main (String args[]){

    	Child c = new Child();
    	c.seeSuper();   
    }
}

public class Parent {

	int i;
	
	Parent(){
		i = 3;
	}
}

public class Child extends Parent{

	Child(){
		//i = 4;  //***
	}
	
	public void seeSuper(){
		System.out.println(super.i);
	}
				
}

note: Parent could also simply look like this:

public class Parent {
	int i = 3;
}
