The biggest new feature of Java 8 is language level support forlambda expressions(Project Lambda). A lambda expression is like syntactic sugar for an anonymous class1with one method whose type is inferred. However, it will have enormous implications for simplifying development. 2.1Syntax The main ...
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...

Fixes an issue that caused the InsertOneResult.getInsertedId() and InsertManyResult.getInsertedIds() methods to return incorrect document IDs in some situations. This change is backported to Java driver v5.1.4 and v4.11.4. When a sharded cluster operation is unsuccessful, the driver avoids sel...
isEmpty(): If a collection is empty, then it returns true. In other words, if the collection doesn't contain elements, this method returns true. Syntax: isEmpty(): boolean iterator(): An iterator is what it gives back. The basic structure is as follows: ...
Range Objects: The range() function returns an iterable that yields a sequence of numbers. It's often used in for loops to specify the number of iterations. for i in range(5): print(i) # prints numbers from 0 to 4 Generators: Generators are a special type of iterable that generate it...
