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 ca
that is, adding n elements requires O(n) time. All of the other operations run in linear time (roughly speaking). The constant factor is low compared to that for the LinkedList implementation.
In the examples, we saw the difference between compile-time and run-time constants. We also saw that the compiler uses compile-time constants to perform static code optimization. Finally, we looked at the usage of compile-time constants in switch statements and Java annotations. As always, the...

JIT Increases level of unpredictability and complexity in Java program. It adds another layer that developers don’t really understand. Example of possible bugs –‘happens before relations’ in concurrency. JIT can easily reorder code if the change is safe for a program running in single thread....

This algorithm avoids large shifts, as in insertion sort, where the smaller value is on the far right and must be moved to the far left. Shell Sort reduces its time complexity by utilising the fact that using Insertion Sort on a partially sorted array results in fewer moves....
through Deep Learning using Python (withKerasandTensorflow), and finally I will present a follow-up of my book, showing how to do the same withDL4Jand/or Keras (with or withoutSpark). I am going to start today with basic stuff, then I am going to add any time more complexity. ...
Given the complexity of accurate timekeeping described above, this Java API defines its own time-scale, theJava Time-Scale. The Java Time-Scale divides each calendar day into exactly 86400 subdivisions, known as seconds. These seconds may differ from the SI second. It closely matches the de fa...
