Another Enthuware question

[Daniel Martins]

  What will be result of attempting to compile this class?

import java.util.*;
package test;
public class TestClass
{
    public OtherClass oc = new OtherClass();
}
class OtherClass
{
    int value;
}  

Is this legal: public OtherClass oc = new OtherClass(); ?

I has the answer rigth (The class will fail to compile)because I assumed the previous line was not legal...however that was not the cause.

The package declaration statement must be the first line of code in class...

Daniel, the order of declaration of classes don't matter, you can declare references of a class even if they are declared after they are used. As far as I remember, in C++ you had to declare a class before it was used, but its not the case in java, so if you got confused because of that, then don't be...

I got confused with the public OtherClass oc = new OtherClass();

I do not remember seing something like this: public A a = new A();

[Ankit Garg]

That's an instance field of the class, it can be declared public, protected, private or default scope i.e. package visible...

My Opinion: The public access modifier is for the object oc, nothing else! If wrong correct!
