Additions In Java 7 For More Beneficial Development

Java development and Java application development is going to be better now for java developers due to amazing new features added in Java 7

. This is the latest and useful version which also brings Jdk7 along with it for making developers project more user-friendly and a time save too. This article shows how useful these changes are and what are they.

Strings: In this version we have new introduction to a type that is used in switch statement. Here this string is of primitive type and enums which enables developers to use the switch functionality to its maximum level instead earlier they had to use strings as key for matching and also had to check for the equals.

Rethrow: Java 7 enables with a broader catch clause here where we have smart compiler so that we can rethrow based on the throw from try block. This feature was not see earlier and

Diamond operator: This one by Java 7 is a cool feature for Java application development as it allows developer to avoid declaration of types. Earlier usage of generics and declaration of map was necessary along with specification of types on both the sides. Diamond operator avoids these specifying and declaring needs.

Easy resources management: Java 7 automates the managing task of resources now in Java development. Often it was earlier confusing and we forget closing streams, readers etc. so we try-catch block for closing the same.

Better Handling: Often handling of exceptions is common which requires multi catching statements for each one to handle. Now with Java 7 no more do we need adding each one and are allowed to add multiple exceptions which is possible to using pipe separator in catch block.

Fork and Join: Heavy and complex operations in Java application development need developers to perform parallel computing. With the introduction of Fork and Join framework in Java 7 it allows developers with distributing of work across various cores and also allows them to get joined after the completion. We are finally with the results after all this and the task is also eased due to division of entire work into smaller sections. All these small tasks can be treated separately using a pool.

More changes we see in Java 7 and useful in Java application development and Java development are notifications in file change, JLayerPane, Numeric literals with underscores, more modular, JSR TBD and JSR 203, Null improvements, Multi-catch, Open JDK, New plug-ins, great user interface, quickstarter, Better protocol, New SDP, Upgraded class loader architecture, new method for closing URLClassLoader, New pipeline for Java 2D, Support for Unicode 5.0, better garbage collector, compressed pointer, multiple virtual machines, JSR 308, updated collections and concurrency, closures, better class properties, overloading of operator, reified generics, BigDecimal syntax, binding of beans and still some more.

The above features are added for better performance of apps, some are customer-oriented so as to benefit them and some are added to ease the task of developers. These features enhance the performance of apps after the java development is finished. Also some support dynamic languages which run the languages in a more efficient way.
