Anonymous inner classes in Java (from Thinking in Java 4th edition) -


i started learning java , there error in line 2: "small cannot resolved type". why?

public class big { public small getsmall() {     return new small() {         void out() {             system.out.println("big small out()");         }     }; }  public static void main(string[] args) {     big b = new big();     small s = b.getsmall();     s.out();     system.exit(0); }

}

public small getsmall() {     return new small() {         void out() {             system.out.println("big small out()");         }     }; }

there seems little misunderstanding. when declare anonymous inner class assumed small either interface implementing or class extending. if have small class or interface need import it. if not create one.
