6. Streams IO Not all IO is block-oriented. There is also stream IO, which is modeled on a pipeline. The bytes of an IO stream must be accessed sequentially. TTY (console) devices, printer ports, and network connections are common examples of streams. Streams are generally, but not neces...
(cat=java streams) since its introduction in java 8, the stream api has become a staple of java development. the basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. but these can also be overused and fall into some common pitfalls. to get...

In this article, we will discuss multiple techniques to slice arrays in Java. From traditional looping methods to leveraging built-in Java functions and Java 8 Streams, this article will provide you with a toolbox of approaches suited for different scenarios. ...
You should invest as much time into the questionHow will people use my software?as you have put intoHow does my software work internally? With a couple of simple tricks you can greatly reduce the developer’s efforts (in terms of the lines of code). ...
The main advantage that the Java NIO package offers is that it's non-blocking, and has channeling and buffering capabilities. When we use the Java IO library we work with streams that read data byte by byte. However, the Java NIO package uses channels and buffers. The buffering and ...
Also, please note that certain Threads are managed internally within the JVM itself such as GC (garbage collection) Threads in order to handle concurrent garbage collections. Since most of the Thread allocations are done by the Java EE container, it is important that you understand and recognize...
Note thatbasicConfig()function can be only called once to configure the root logger. If you don’t configuredebug(),info(),warning(),error(), andcritical()functions when calling thebasicConfig()function, default values will be assigned to them internally and you won’t be able to configure ...
