java invoke static method from instance method & from static class call -

i have class static method invoked same class method , other class using class.staticmethod. this,

classa{  public void method1(){      ---      ---      method2();  }  public static void method2(){     ---     ---  } }  classb{   public void call(){     classa.method2(); //i have invoke through static method.   } }  public void main(...){  classa obj = new classa();  obj.method1(); } 

is code follow standard (section 10.2 of java conventions)? or should invoke classa.method2() in classa method1. please dont duplicate, have looked @ other questions, don't talk scenario.

• invoke static method using this.method vs classname.method
• java convention on reference methods , variables

as the conventions state (thanks makoto), should refrain using object reference call static method. means, not this:

someobject.staticmethod(); 

instead, use class name this:

someclass.staticmethod(); 

of course, if calling static method within class ok (and preferred) this:

staticmethod();
