Repeating Annotations – It is now possible to apply the same annotation type more than once to the same declaration or type use.įor more information on Java 8 enhancements, you may find this document useful.

Used in conjunction with a pluggable type system, this allows for stronger type checking of your code.

Annotations on Java Types – It is now possible to apply an annotation anywhere a type is used.

The most prominent example is using a method invocation’s target types to infer the data types of its arguments. However, in Java SE 8, you can use the target type for type inference in more contexts. For example, you can use an assignment statement’s target type for type inference in Java SE 7. The target type of expression is the data type that the Java compiler expects to depend on where the expression appears.

Improved Type Inference – The Java compiler takes advantage of target typing to infer the type parameters of a generic method invocation.

You can use a lambda expression if you want a certain action performed on each element of a collection, when a process is completed, or when a process encounters an error.

Lambda Expressions enable you to encapsulate a single unit of behavior and pass it to another code.

Users should feel more secure once they update to Java 8 which is the most secure version of Java to date. Most of the enhancements and updates in Java 8 are related to the programming language. Recently Java has been a victim of quite a few vulnerabilities but Oracle has bounced back by releasing security updates to the language and the runtime environment regularly.

It powers mobile devices as well as gives dynamic functionality to websites. Java is a popular language which is used for a wide variety of purposes. Here is another post about offline installers of Java 8 which has recently been released.
