Question

A.java

package a;
class A {

    void f1()
    {
        System.out.println("hi");
    }
}  

---

B.java

In same folder as of A.java and class files are generated in the same folder.

package b;
class B
{
    new A().f1();
}

I am new to package concept. My question here is even though they are not in the same package how can B create the object of A?

Answer 1

If you use public class declaration it goes to public access level. Public classes can be accessed by different packages by using import a.A; or providing the complete class name new a.A().f1().
