How this method is called without using the classname

Question

I wanted to know how a static method is called in another class.

Assume I have a class as following,

class classA
{
public static void method1(String a)
{
}
}

In another class the method method1 is called as following,

class classB
{
public static void main(String[] args)
{
 method1("Alpha");
 }
 }

Please note that the ClassB is not extending the ClassA, I am confused.

One more thing, always [indent your code](http://en.wikipedia.org/wiki/Indent_style) — Grijesh Chauhan, Jun 09 '13 at 10:12

You can use a static import:

import static yourpackage.classA.method1;

If you are working in default package, the import will fail, see: https://stackoverflow.com/a/1964006/2039482

Side note: Class names are conventionally always starting with an upper case letter

If you have in your class B static import yourpacage.ClassA you can call static methods without writting the class name.

If the two classes are in the same package you don't have to import them you can simply go:

Classname.methodName(possibleParameter);

If not in the same package import the package as mentioned by Bernhard Poiss.

i can't see how something like this can happen, unless:

classB is a static inner class of classA or something of that sort.
you have a static import somewhere (and that works only if you place the classes inside a package).
