Are these two method calls the same?

Question

Code blocks number 1.

public class SomeClass {
    public static void main(String [] args) {
        SomeClass foo = new SomeClass();
        foo.SomeMethod();
    }
    public void SomeMethod() {

    }
}

Code blocks number 2.

public class SomeClass {
    public static void main(String [] args) {
       new SomeClass().SomeMethod();
    }
    public void SomeMethod() {

    }
}

Are this two code blocks(number 1 and 2) the same? I'm confused over the different syntax during calling the method. I appreciate if someone could explain it for me.

Yes, they are functionally the same. With code block 2, however, you have no way of accessing the SomeClass object you created in the future lifespan of the program.

There's no way to access it in the future in either case; foo is being discarded. – alzee Aug 02 '16 at 15:14

Yes they are same. In first case the object reference is just stored in a reference variable for future usage .
In second case the reference is not stored.
