In order to understand what a Stream is, it is first worth considering a "normal" Iterator for comparison. Prior to Java 8, we could have obtained an Iterator over a collection of objects as follows:List<String> list = ...some list... Iterator<String> it = list.iterator(); ...
Java SE 8 generalized this concept one step further, outside collections, by lifting it into its own interface: Stream. Stream. Like several other interfaces in the JDK, the Stream interface is a fundamental interface that is intended for use in a variety of scenarios, including the ...
The significant new language feature in Java SE 8 is the introduction of Lambda expressions, a way of defining and using anonymous functions. On its own this provides a great way to simplify situations where we would typically use an inner class today. However, Java SE 8 also introduces a ...

It also has new types to handle dates in Java 8, which can be converted and bound to components. Why Wicket only partially supports lambdas Wicket’s developers decided against supporting lambdas in the API because of performance and memory usage considerations. Thus, subclassing remains the ...
On the first line, you define a supplier for<java.time.LocalTime>types calledtimeSupplier. It is assigned to a lambda which has no parameters and its execution code returns the current time as provided by the built-injava.time.LocalTime.nowmethod. Finally, you use thegetmethod to get the...
