Java-Stream

We use the Java Stream map (an intermediate operation) to map an element in a stream to a different value (of the same or different type).

In this post, we will learn about using Java Stream min and max methods to find the minimum and the maximum element in a Java Stream.

Using Java Stream sorted operation on a stream will return a stream with the elements of the stream sorted according to their natural order.

We use the Java Stream’s reduce method to reduce a stream of values to a single result. There are three overloaded Stream#reduce operation.

The Java Stream mapMulti method was added in Java 16. It allows us to replace each element in a Java Stream with one or more elements.

In this post, we will see the three ways to sum a stream of numbers (using Java streams). We use the mapToInt, reduce, and collect methods.
