public class LambdaDemo
{

    public static void main(String[] args)
    {
        printLambda(str -> str.length());
    }

    private static void printLambda(StringLengthLambda stringLengthLambda)
    {
        int length = stringLengthLambda.getLength("Welcome");
        System.out.println("length = " + length);
