Java Array Map Lambda

Java 8 java arrays sorting algorithms in this tutorial, we will see how to sort an array of objects in ascending and descending order using java 8 lambda expressions. We have passed character and runnable arguments to map object and pass a lambda expression as the second argument in the put () method of map class. Map () converts the elements and collect (.) or toarray () wrap the stream back up into an array or collection.

@timb probably because there is no unique interface the lambda maps to. The array.map () method allows you to iterate over an array and modify its elements using a callback function. Lamda's reduces code to very minimal to our core logic and remaing take care by lamda.

Below is the implementation of the above approach.

In this tutorial, we will see how to iterate (loop) map and list in java 8 using lambda expression. The problem is that the lambda could be different from each other. @timb probably because there is no unique interface the lambda maps to. In the below example, we can populate a map using a lambda expression.
