I have trouble with static variables. 

Some static variables seem to be initialized several times. So, I lost
values stored before.

The example is as follows:

class Foo {
   public static String foo = "init";     // --------(1)
}


class SomeClass {
   public void setFoo() {
       Foo.foo = "SomeClass";
   }
}


class AnohterClass {
   public String getFoo() {
       return (Foo.foo);
   }
}

If I invoke getFoo() method after invoking setFoo() , the result should
be "SomeClass", but
sometimes it returns "init".  I found the initialization process (1)
executed twice, 
but I don't know how to avoid it. Could anyone tell me?
