javax.imageio.stream A package of the Java Image I/O API dealing with low-level I/O from files and streams. Java 8 introduced stream which is a sequence of elements supporting sequential and parallel aggregate operations. In addition it helped introduce a functional programming style to java. It is a possible that a stream has unordered elements so this tutorial is not to be confused with sorting a stream in reverse order.Let's find out how to flip the elements in the stream while maintaining order. To overcome these limitations Java 8 introduced a new additional package called java.util.stream which consists of classes, interfaces and enum to allow functional-style operations on the elements.
