IntStream peek() method in Java
The peek() method in the IntStream class in Java returns a stream consisting of the elements of this stream. It additionally performs the provided action on each element as elements are consumed from the resulting stream.The syntax is as followsIntStream peek(IntConsumer action)Here, the parameter action is a non-interfering action to perform on the elements as they are consumed from the stream. The IntConsumer represents an operation that accepts a single int-valued argument and returns no result.The following is an example to implement IntStream peek() method in JavaExampleimport java.util.*; import java.util.stream.IntStream; public class Demo { public static void ...

The contains() method of AbstractSequentialList in Java is used to check whether an element is in the Collection.The syntax is as followspublic boolean contains(Object ob)Here, ob is the element to be checked. To work with the AbstractSequentialList class in Java, you need to import the following packageimport java.util.AbstractSequentialList;The following is an example to implement AbstractSequentialList contains() method in JavaExampleimport java.util.LinkedList; import java.util.AbstractSequentialList; public class Demo { public static void main(String[] args) { AbstractSequentialList absSequential = new LinkedList(); absSequential.add(250); absSequential.add(320); ...
Read MoreIntStream forEachOrdered() method in Java
The forEachOrdered() method in Java assures that each element is processed in order for streams that have a defined encounter order.The syntax is as followsvoid forEachOrdered(IntConsumer action)Here, the action parameter is a non-interfering action to be performed on the elements.Create an IntStream and add elements to the streamIntStream intStream = IntStream.of(50, 70, 80, 100, 130, 150, 200);Now, use the forEachOrdered() method to display the stream elements in orderintStream.forEachOrdered(System.out::println);The following is an example to implement IntStream forEachOrdered() method in JavaExampleimport java.util.*; import java.util.stream.IntStream; public class Demo { public static void main(String[] args) { ...

The DoubleStream class in Java the following two forms of the of() methodThe following of() method returns a sequential DoubleStream containing a single element. Here is the syntaxstatic DoubleStream of(double t)Here, parameter t is the single element.The following of() method returns a sequential ordered stream whose elements are the specified valuesstatic DoubleStream of(double… values)Here, the parameter values are the elements of the new stream.To use the DoubleStream class in Java, import the following packageimport java.util.stream.DoubleStream;The following is an example to implement DoubleStream of() method in JavaExampleimport java.util.stream.DoubleStream; public class Demo { public static void main(String[] args) { ...
Read MoreThe toArray(T[] a) method of CopyOnWriteArrayList in Java
The difference between toArray() and toArray(T[] arr) of the CopyOnWriteArrayList class is that both the methods returns an array containing all of the elements in this collection, but the latter has some additional features i.e. the runtime type of the returned array is that of the specified array.The syntax is as followspublic T[] toArray(T[] arr)Here, the parameter arr is the array into which the elements of the list are to be stored.To work with CopyOnWriteArrayList class, you need to import the following packageimport java.util.concurrent.CopyOnWriteArrayList;The following is an example to implement CopyOnWriteArrayList class toArray() method in JavaExampleimport java.util.Arrays; import java.util.concurrent.CopyOnWriteArrayList; ...
