How to call none static method java in Cocos Creator

Cocos Creator
#1

i can call static methods with

jsb.reflection.callStaticMethod

but what about none static functions ?
is it possible call a none static function in js side ?

#2

i find a tricky way , only need simple java knowledge …
its need create a new instance from class and then call none static method in a static method.

public static void staticMethod(){
         ClassName temp = new ClassName()
            temp.noneStaticMethod()
}
