Java 8 is a giant step forward for the Java language. Writing this book has forced me to learn a lot more about it. In Project Lambda, Java gets a new closure syntax, method-references, and default methods on i

As usual, parenthesizing of an expression containing = operator is not allowed. Hence the syntax error in (a, b = 6, 9). The syntax of the Walrus operator is of the form NAME:= expr, where NAME is a valid identifier, and expr is a valid expression. Hence, iterable packing and unp...

Linux: Install libmongocrypt.so directly on the file system, instead of using the file that is bundled within the mongodb-crypt JAR file. You can find Linux instructions to install libmongocrypt in the Server manual. If you use a package manager to install libmongocrypt, Java Native Access...
The Collection interface expands the Iterable interface. There is only one method called iterator in the iterable interface (). The iterator method's purpose is to return the iterator object. We can iterate through the collection's elements using this iterator object. ...
Understanding for loop in Python The for loop in Python is used to iterate over a sequence (like a list, tuple, or string) or other iterable objects. Iterating over a sequence means going through each element one by one. In this article, we’re going to describe how to iterate over a...
Had they introduced Java 8 lambda expression without default method likeforEach()onjava.lang.Iterable, It wouldn't help in the development of parallel libraries, which is the core intention of introducing lambda expression to exploit the capability of multiple CPUs available in modern computers. ...
