      Scanner in = new Scanner(System.in);

      n = in.nextInt();

      System.out.println("Multiplication table of "+n+" is :-");

      for ( c = 1 ; c <= 10 ; c++ )

Lambda in Java 8

Lambda Expression in Java

Quick notes on How to use the Lambda feature in new Java

Lambda expressions are a new and important feature included in Java SE 8. They provide a clear and concise way to represent one method interface using an expression. Java code can be improved with the inclusion of lambda expressions.

Syntax of Lambda Expression

(argument) -> (body)

A lambda expression is composed of three parts.

Argument List Arrow Token          Body

(int x, int y)             ->                     x + y

Simple Example for Lambda Expression

(int x, int y) -> x + y

() -> 42

(String s) -> { System.out.println(s); }

           The first expression takes two integer arguments, named x and y, and uses the expression form to return x+y. The second expression takes no arguments and uses the expression form to return an integer 42. The third expression takes a string and uses the block form to print the string to the console, and returns nothing.
