Method references provide easy-to-read lambda expressions for methods that already have a name. Default methods enable new functionality to be added to the interfaces of libraries and ensure binary compatibility with code written for older versions of those interfaces. 允许我们给接口添加一个非抽象的...
From an array viaArrays.stream(Object[]); From static factory methods on the stream classes, such asStream.of(Object[]),IntStream.range(int, int)orStream.iterate(Object, UnaryOperator); The lines of a file can be obtained fromBufferedReader.lines(); ...
Default Methods for Interfaces Java 8 enables us to add non-abstract method implementations to interfaces by utilizing thedefaultkeyword. This feature is also known asvirtual extension methods. Here is our first example: interface Formula { double calculate(int a); default double sqrt(int a) { r...
This class consists ofstaticutility methods for operating on objects. Observable This class represents an observable object, or "data" in the model-view paradigm. Optional<T> A container object which may or may not contain a non-null value. ...
The java.util.concurrent.Executors class provides several utility methods, such as providing pre-configured executors or wrapping plain old java.lang.Runnable objects into instances of Callable. The advantage of using Callable over Runnable is that Callable can explicitly return a value. This example ...

DeflaterOutputStream.close() and GZIPOutputStream.finish() methods have been modified to close out the associated default JDK compressor before propagating a Throwable up the stack. ZIPOutputStream.closeEntry() method has been modified to close out the associated default JDK compressor before propagatin...
As always, arrays in Java are real objects that know their own length, so String objects in Java don’t require special terminators (not even internally). If you need to know the length of a String, use the length( ) method: int length = quote.length( ); Strings can take advantage...
