Lambda Expressions in java : Lambda expressions basically express instances of functional interfaces (An interface with single abstract method is called functional interface. An example is java.lang.Runnable). lambda expressions implement the only abstract function and therefore implement functional interfaces lambda expressions are added in Java 8 and provide below functionalities. Enable to treat functionality as a method argument, or code as data.A function that can be created without belonging to any class.A lambda expression can be passed around as if it was an object and executed on demand.Example :class Test { public static void main(String args[]) { // lambda expression to implement above // functional interface. This interface // by default implements abstractFun() FuncInterface fobj = (int x)->System.out.println(2*x); // This calls above lambda expression and prints 10. fobj.abstractFun(5); } } - Study24x7
