Java 8 Interface Pollution; Topics: java, enterprise-integration, functional programming, client-side, java8. Published at DZone with permission of Edwin Dalorzo. JAVA 8 is a major feature release of JAVA programming language development. Its initial version was released on 18 March 2014. With the Java 8 release, Java provided supports for functional programming, new JavaScript engine, new APIs for date time manipulation, new streaming API, etc. To tackle this issue, Java 8 has the introduction of default methods. It might sound surprising but interface can have implementation code as well. You can declare default method in the interface and it won’t force client to implement default method. For example: reversed is default method in Comparator interface. Java Runtime Environment (JRE) is Java’s most basic virtual machine. It’s a required component to run any Java-based application or web applet. Java software allows you to run applications called 'applets' that are written in the Java programming language. These applets allow you to have a much richer experience online than simply.

New Features
Lambda expression − Adds functional processing capability to Java.
Method references − Referencing functions by their names instead of invoking them directly. Using functions as parameter.
Default method − Interface to have default method implementation.
New tools − New compiler tools and utilities are added like ‘jdeps’ to figure out dependencies.
Stream API − New stream API to facilitate pipeline processing.
Date Time API − Improved date time API.
Optional − Emphasis on best practices to handle null values properly.

JDK Mission Control (JMC) is an advanced set of tools formanaging, monitoring, profiling, and troubleshooting Javaapplications. JMC enables efficient and detailed data analysis forareas such as code performance, memory, and latency withoutintroducing the performance overhead normally associated withprofiling and monitoring tools.
JDK Mission Control version 8.0.1 (JMC 8) is now available fordownload. JMC 8 delivers a new flame graph view, enhanced Rules APIalong with other improvements to functionality and usability. JMC 8supersedes JMC 7, all JMC 7 users and any remaining JMC 5 usersshould upgrade to this new version. JMC 8 is now able to analyzerecordings from JDK 7 and above.
