Your syntax is wrong;
Interface f = () -> System.out.println("test");
質問
Nothing seems weird here: 2Classes. Interface.java and Lambdas.java
public class Lambdas {
public static void main(String[] args) {
new Lambdas().start();
}
public void start(){
Interface f = () -> Interface{System.out.println("test");}
}
}
public interface Interface {
void test();
}
I get error: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - cannot find symbol symbol: variable Interface location: class lambdas.Lambdas . I don't know why.
P.S. Just arrived home from Java Day 2014 , I use their examples - with netbeans
