Following is the problem from CertPal



What is the output ?

    
public class Toast extends Boast 
{
    Integer eye=1;
    public static void main(String... args)
    {
        Toast eye = new Toast(); 
        new Devil(eye).honey(eye);
        new Boast(eye).honey(eye);
        new Toast().honey(eye);
    }
    public void honey(Toast eye)
    {
        eye.eye = new Integer(-2);
    }    
    
}

class Boast extends Devil 
{
    public Boast(){System.out.print("boast ");}
    public Boast(Toast eye)
    {
        eye.eye = new Integer(5);
    }
    
    public void honey(Toast eye)
    {
        eye.eye = new Integer(2);
    }
}

class Devil
{
    public Devil(){System.out.print("devil ");}
    public Devil(Toast eye)
    {
        eye.eye = new Integer(1);
    }
    public void honey(Toast eye)
    {
        eye.eye = new Integer(9);
    }    
}

the answer given is devil boast devil devil boast
but when i ran this code i got error "non static variable can not be refrenced from a static context

if i ignore this error and apply the rule "each constructor call its super counstructor" i think the answer will be "devil boast devil devil boast devil boast".

Please correct me and explain if i am wrong

Did you try to run the code as is ? Sure ?

Hint: Which variable is 8.)# new Devil(eye).honey(eye); referring to ? The member variable or the local variable ?

[Seetharaman Venkatasamy]

you wont get any compiler error. because *Integer eye is shadowed by Toast eye* .

output will be *devil boast devil devil boast*[analyse yourself]
