java - Can I Create Object For Interface? -

is possible creating object interface, if yes how can we? according view following code says can:

runnable r= new runnable(){ // implementation }

this not creating instance of interface, creating class implements interface. when write

    runnable runnable = new runnable() {          @override         public void run() {             // todo auto-generated method stub          }     }; 

you creating class implementing runnable interface. need follow rules here, here, overriding run method runnable

 there similar thing abstract class also. can test using example  public abstract class abstractclass {      public void somemethod(){         system.out.println("abstract class");     }  } 

and class i.e. testclass

public class testclass {      public static void main(string[] args) {          abstractclass abstractclass = new abstractclass() {             public void somemethod() {                 system.out.println("concrete class method");             }         };         abstractclass.somemethod();     } } 

this create instance of subclass in overriding somemethod(); program prints

concrete class method 

this proves creating instance of subclass.
