![]() The Java Cryptography Extension (SunJCE) provider is enhanced to support AES/GCM/NoPadding cipher implementation as well as Galois/Counter Mode (GCM) algorithm parameters.Ħ) A new command flag -importpassword is added to the keytool utility. The SNI extension is a feature that extends the SSL/TLS protocols to indicate what server name the client is attempting to connect to during handshaking.ĥ) The SunJSSE is enhanced to support Authenticated Encryption with Associated Data (AEAD) algorithms. It is an overloaded method.ġ) The Java Secure Socket Extension(JSSE) provider enables the protocols Transport Layer Security (TLS) 1.1 and TLS 1.2 by default on the client side.Ģ) A improved method AccessController.doPrivileged has been added which enables code to assert a subset of its privileges, without preventing the full traversal of the stack to check for other permissions.ģ) Advanced Encryption Standard (AES) and Password-Based Encryption (PBE) algorithms, such as PBEWithSHA256AndAES_128 and PBEWithSHA512AndAES_256 has been added to the SunJCE provider.Ĥ) Java Secure Socket Extension (SunJSSE) has enabled Server Name Indication (SNI) extension for client applications by default in JDK 7 and JDK 8 supports the SNI extension for server applications. The parallelSort() method has added to class that uses the JSR 166 Fork/Join parallelism common pool to provide sorting of arrays. Java provides a new additional feature in Arrays class which is used to sort array elements parallelly. This class provides three different encoders and decoders to encrypt information at each level. You need to import 64 class in your source file to use its methods. Java provides a class Base64 to deal with encryption and decryption. This method takes predicate as an argument and returns a stream of resulted elements. Suppose, you want to get only even elements of your list, you can do this easily with the help of filter() method. ![]() Java stream provides a method filter() to filter stream elements on the basis of given predicate. Java 8 package consists of classes, interfaces and an enum to allow functional-style operations on the elements. It provides reduction operations, such as accumulating elements into collections, summarizing elements according to various criteria etc. Now, you can create string by passing delimiters like comma(,), hyphen(-) etc.Ĭollectors is a final class that extends Object class. It is used to construct a sequence of characters separated by a delimiter. Java added a new final class StringJoiner in java.util package. You can execute JavaScript code by two ways: Java provides a command-line tool jjs which is used to execute JavaScript code. It is used to execute JavaScript code dynamically at JVM (Java Virtual Machine). These methods are non-abstract methods and can have method body. Methods which are defined inside the interface and tagged with default keyword are known as default methods. Java provides a facility to create default methods inside the interface. The java.time package contains Java 8 Date and Time classes. Java has introduced a new Date and Time API since Java 8. So, you can pass lambda expression as an argument. This method takes a single parameter which is a functional interface. Collection classes which extends Iterable interface can use forEach() method to iterate elements. It is a default method defined in the Iterable interface. ![]() ![]() It is defined in Iterable and Stream interfaces. Java provides a new method forEach() to iterate the elements. It provides methods to check the presence of value for particular variable. We must import java.util package to use this class. It is a public final class which is used to deal with NullPointerException in Java application. Java introduced a new class Optional in Java 8. It can also declare methods of object class.įunctional interfaces are also known as Single Abstract Method Interfaces (SAM Interfaces). It can have any number of default and static methods. Each time when you are using lambda expression to just referring a method, you can replace your lambda expression with method reference.Īn Interface that contains only one abstract method is known as functional interface. It is compact and easy form of lambda expression. Java 8 Method reference is used to refer method of functional interface. It is very useful in collection library in which it helps to iterate, filter and extract data.įor more information and examples: click here It provides a clear and concise way to implement SAM interface(Single Abstract Method) by using an expression. Lambda expression helps us to write our code in functional style. Java 8 provides following features for Java Programming: It includes various upgrades to the Java programming, JVM, Tools and libraries. It was a revolutionary release of the Java for software development platform. Oracle released a new version of Java as Java 8 in March 18, 2014.
