Starting from C# 7.0 the throw keyword can be used both as an expression and as a statement, which is nice. Though, consider these overloads
I am using this to sort but it is giving an error.This is also giving an error.You could sort the input of type Integer as :
I have a List of Strings and a Map. Every key in the map needs to present in the list else I need to throw an exception. As of now I am looping the list and checking the key and throw exception if the map doesn't contains the key. Below...
I would like to optimize the below code to take an existing ArrayList and make a new list based on the below logic. Does streaming/lambda in Java 8 make it possible?
Note: this question is not related to java.util.Optional.When dealing with streams, I often use logic like this:
How can i write below code using lambda expression in java8. I am new to Java 8. I have tried the below code as yet as per the suggestion . Is there any other thing which we can improve in this code to write it using lambdas more.
Why doesn't the first of the following examples work?Both examples are compiled-able.The output is:In the first example the R constructor is called, it returns lambda (which is not object):
I have List object and I need to take the first element on the list if it is not null or empty. I write below code using java and now I want to convert it to Java 8.
Let's suppose there is a Fox class, which has got name, color and age. Let's assume that I have a list of foxes, and I want to print out those foxes' names, whose colours are green. I want to use streams to do so.
I am trying to get closer to understanding streams thus I'm doing some basic exercises. In this one, I'd like to calculate the average of the odd numbers. I wrote this algorithm to do so, but it gives back an incorrect result (8.0). I've tried to debug it but I...
