(原文:Programs where threads hold (directly or indirectly) locks on multiple objects should use conventional techniques for deadlock avoidance, creating higher-level locking primitives that do not deadlock, if necessary.) java 还提供了其他的一些同步机制,比如对 volatile 变量的读写、使用 java.util.co...

Java 8 provides following features for Java Programming: Lambda expressions, Method references, Functional interfaces, Stream API, Default methods, Base64 Encode Decode, Static methods in interface, Optional class, Collectors class, ForEach() method, ...
4. Java Stream API for Bulk Data Operations on Collections A newjava.util.streamhas been added in Java 8 to perform filter/map/reduce like operations with the collection. Stream API will allow sequential as well as parallel execution. This is one of the best features for me because I work...
Allow applications to configure context-specific and dynamically-selected deserialization filters via a JVM-wide filter factory that is invoked to select a filter for each deserialization stream. The behavior is a strict subset of JEP 415: Context-Specific Deserialization Filters to allow a filter fact...

Programs usebyte streamsto perform input and output of 8-bit bytes. All byte stream classes are descended fromInputStreamandOutputStream. There are many byte stream classes. To demonstrate how byte streams work, we'll focus on the file I/O byte streams,FileInputStreamandFileOutputStream. Other...
With Java 8, there is performance improvement for HashMap with Key collisions. Classes in java.util.stream package provides Stream API in supporting functional style operations on a stream of elements. It has SSL or TLS Server name indication extension support in the server, with SHA 224 message...
