Java 8: The Latest Java Development Language

The most recent Java release, Java 8, includes new features, improvements, and bug fixes to increase the speed with which Java programs may be created and executed. Before being made accessible for download by end-users on the website, the new release of Java is first made available to developers so they have enough time for testing and certification.

Here are the latest features of Java 8:

Oracle JDK 7: Auto-update Notice and End of Public Updates

Users having the auto-update feature turned on are urged to upgrade from Java 7 to Java 8 as of the January 2015 Critical Patch Update release. Please take note that the April 2015 CPU release will be the final publicly accessible upgrade for Java 7. Before upgrading to Java 8, consult the app developer. Some application developers could insist that you utilize a specific Java release even though they have not certified their programs for Java 8. If you have trouble running an application using Java 8, check with the developer of the program to see if it has been approved for this version.

Aspects of Java 8

An overview of the improvements made available with the Java 8 version is provided below:

  • Virtual Extension Methods and Lambda Expression
  • The addition of Lambda expressions and associated functionality to the Java platform and language is the standout feature of Java SE 8.
  • API for Date and Time
  • Developers will be able to handle dates and times in a more natural, cleaner, and understandable way thanks to this new API.
  • JavaScript Engine Nashhorn

Through already-existing APIs, Java applications can access a new, lightweight, high-performance implementation of the JavaScript engine that has been integrated into JDK.

Enhanced Security

The system that accurately identifies such methods and enables the reliable discovery of their callers should be used in place of the current manually kept list of caller-sensitive methods.

Security Improvements in Java 8

1) The Transport Layer Security (TLS) 1.1 and TLS 1.2 protocols are enabled by default on the client-side via the Java Secure Socket Extension (JSSE) provider.

2) A better technique With the addition of AccessController. Privileged, code can now assert a portion of its privileges while still allowing a full-stack traversal to check for other rights

3) The SunJCE service now offers the Advanced Encryption Standard (AES) and Password-Based Encryption (PBE) algorithms PBEWithSHA256AndAES 128 and PBEWithSHA512AndAES 256.

4) Server Name Indication (SNI) extension is supported for server applications in JDK 8 and is enabled by default for client applications in JDK 7’s Java Secure Socket Extension (SunJSSE). The SSL/TLS protocols are extended by the SNI extension, which allows users to specify

The SNI extension is a feature that allows clients to specify the server name they are trying to connect to during handshaking using the SSL/TLS protocols.

5)Authenticated Encryption with Associated Data (AEAD) techniques are supported by improved SunJSSE. The Galois/Counter Mode (GCM) algorithm parameters and the AES/GCM/NoPadding cipher implementation are now supported by the Java Cryptography Extension (SunJCE) provider.

6) The key tool utility now has a new command flag called import password. It is utilized to recognize passwords and safely store them as secret keys. similar to classes. Java. security and DomainLoadStoreParameter To support the DKS Keystore type, PKCS12Attribute is added.

7) SHA-224, a member of the SHA-2 family of message-digest implementations, has been added to JDK 8 to improve the cryptographic algorithms.

8) Better NSA Suite B Cryptography support, which includes:

NSA Suite B cryptography methods OID registration

support for the creation of 2048-bit DSA key pairs and additional signature algorithms, such as SHA224 with DSA and SHA256 with DSA.

lifting the Diffie-Hellman (DH) algorithm’s keysize restriction from 1024 to 2048.

9) The SecureRandom class offers the creation of random numbers that are cryptographically secure and are utilized for private or public keys, ciphers, and signed messages.

  • JDK 8 introduced the getInstanceStrong() method, which returns an instance of the strongest SecureRandom. When you need to generate an RSA private key and public key, you should use it. Other changes made by SecureRandom include the following:
  • For UNIX platforms, there are now two new implementations that offer blocking and non-blocking behavior.

10) A new PKIXRevocationChecker class is added, which examines the PKIX algorithm-based certificates’ revocation status. It offers mechanisms-specific settings, end-entity certificate validation, and best-effort verification.
