title: How can i call an non static method of Abstract class
body: <p>How can i call an non static method of Abstract class, without using its sub class or extends it because abstract class and sub class is too complex so i do not want to cause any side effect. </p>
  
  <p>for example concrete static methods of an abstract class can be call with class name an dot operator, without creating sub class. Similar is there any way to call a non static method. </p>
  
  <p>i just want to run a method and i do not want run any other code. i tried to use reflection but it requires instance</p>
