package com.codeFactory.methodAndConstructorReference;
class Sample {
 Sample() {
  System.out.println("Sample.Sample()");
 }
}
interface Interf {
 public Sample get();
}
// Using Lambda Expression
public class Test {
 public static void main(String... args) {
  Interf i = () -> {
   return new Sample();
  };
  Sample s = i.get();
 }
}
// Using Constructor Reference
public class Test {
 public static void main(String... args) {
  Interf i = Sample::new;
  Sample s = i.get();
 }
}

Output :

Sample.Sample()

Syntax for Constructor Reference :

• classname :: new
• e.g. Sample :: new
