Concatenating parallel streams
Suppose that I have two int[] arrays input1 and input2. I want to take only positive numbers from the first one, take distinct numbers from the second one, merge them together, sort and store into the resulting array. This can be performed using streams: int[] result = IntStream.concat(Arrays.stream(input1).filter(x -> x > 0), Arrays.stream(input2).distinct()).sorted().toArray(); I want to speed u

JEP 286: Local-Variable Type Inference
Summary Enhance the Java Language to extend type inference to declarations of local variables with initializers. Goals We seek to improve the developer experience by reducing the ceremony associated with writing Java code, while maintaining Java's commitment to static type safety, by allowing developers to elide the often-unnecessary manifest declaration of local variable types.
