Java is one of the languages of the Internet. There are webpages and other components that require Java Runtime Environment in order to run the embedded components inside them. Developers need Java Development Kit in order to develop programs in Java language.
For quite a long time, Java has been a target of hackers and vulnerabilities but now Oracle has done quite a lot of work by updating Java multiple times and removing the vulnerabilities in Java.
It is always recommended that you have the latest version of Java installed so that you remain completely secure from the vulnerabilities of previous versions.
Java 8 Update 31 has been released and is ready for download from Oracle’s website. We will provide the direct download links to Java 8 Update 31 after discussing about what’s new in the latest release.

If SSLv3 is absolutely required, the protocol can be reactivated by removing “SSLv3” from thejdk.tls.disabledAlgorithms property in the java.security file or by dynamically setting this Security property to “true” before JSSE is initialized.
It should be noted that SSLv3 is obsolete and should no longer be used.
Changes to Java Control Panel
Starting with JDK 8u31 release, SSLv3 protocol is removed from Java Control Panel Advancedoptions.
If the user needs to use SSLv3 for applications, re-enable it manually as follows:
Enable SSLv3 protocol on JRE level: as described in the previous section.
Enable SSLv3 protocol on deploy level: edit the deployment.properties file and add the following:
