in java $17\mathrm{.}4$ Fill in the blanks in each of the following statements:

Stream $$ are formed from stream sources, intermediate operations and terminal operations.

The following code uses the technique of $$ iteration:

$1$ int sum $=0$;

$2$

$3$ for $($int counter $=0$; counter $<$ values.length; counter$++)\{$

$4$ sum $+=$ values$[$counter$]$;

$5\}$

Functional programming capabilities focus on $$not modifying the data source being processed or any other program state.

An implementation of the functional interface $$ takes a T argument and returns void, and performs a task with its T argument, such as outputting the object, invoking a method of the object, etc.

An implementation of the functional interface $$ takes no arguments and produces a value of type T$$this is often used to create a collection object in which a stream operation$$s results are placed.

Streams are objects that implement interface Stream and enable you to perform functional programming tasks on $$ of elements.

The intermediate stream operation $$ results in a stream containing only the elements that satisfy a condition.

$$ place the results of processing a stream pipeline into a collection such as a List, Set or Map.

Calls to filter and other intermediate streams are lazy$$they aren$$t evaluated until an eager $$ operation is performed.

Pattern method $$ uses a regular expression to tokenize a String and create a stream.

Functional interfaces must contain only one method, but may also contain $$ and static methods that are fully implemented in the interface declarations.
