Calling method without object

Question

I have built a small (and 3 methods only!) api for myself, and I want to be able to call it like how you would call a method in Powerbot (A Runescape botting tool (I use it, but for programming purposes, not for actual cheating purposes)), without creating an Object of the file you'd require. How would i be able to do this?

You will need to create static methods, so you will need to do something like so:

public class A
{
    public static void foo()
    {
        ...
    }
}

And then, you can call them like so:

public class B
{
    ...
    A.foo();
}

Note however that static methods need to be self contained.

EDIT: As recommended in one of the answers below, you can make it work like so:

package samples.examples
public class Test
{
    public static void A()
    {
        ...
    }
}

And then do this:

import static sample.examples.Test.A;

public class Test2
{
    ...
    A();
}

What i'm asking is, is it possible to be able to call them, without having any kind of declaration? Like using the "A.foo();" Is it possible to just call it like foo();? – Nathan Kreider May 31 '12 at 08:33
@Nathan: To just call `foo()` you will need to place it in the same class. – npinti May 31 '12 at 08:42
So there's no way at all to get rid of the class declaration? – Nathan Kreider May 31 '12 at 08:43
@NathanKreider: What you are after seems after all possible. I have ammended my answer. – npinti May 31 '12 at 08:48

If you use the static keyword when importing your class, you can use its methods as if they belong to the class you're importing them to. See:

http://docs.oracle.com/javase/1.5.0/docs/guide/language/static-import.html

And of course your "api methods" need to be static as well.

The prerequisite of this is declaring the desired class members `static`. – Péter Török May 31 '12 at 07:04

The best way i found out for me was to extend my activity (If i said it right)...

MAIN CLASS

public class myMainActivity extends myMiniApi{
...
}

I think this is a better way (my opinion) to do this, Just call your method like you normally would as if it were in the same class. example:

randomMethod();

Calling method without object
