There is no usual "function" in java?

Question

in php you can declare a function in a global scope using a function.

Is this impossible in java? It looks like every function is in the class as a method. so what is all oop in java? no procedural code?

Answer 1

The closest thing you can use for a "free-floating" function is a static function, which you can call qualified with a class name, for example.

public class Foo {
   public static void bar(){}
}

... in the other place

Foo.bar();

You can add a little syntactic sugar to this to make it look what you think:

import static Foo.bar;

... in the other place

bar();
