Make software development easier with Java 7
Java 7 has been in the software development world for quite some time now. The variety of features, bug fixes as well as enhancements in it has led to improved efficiency in the development as well as running of Java programs when compared to Java 6. In fact, many developers have a love-hate relationship with the next version; but about the benefits of this particular version almost all of those people are unanimous. There are many features that have led to this intense popularity. Some of them have been discussed here.
One catch block with multiple exception- The very first feature that most people have fallen in love with when using this version is the fact that multiple Exception can be caught in a single catch block. This feature known as multicatch block is an important feature in Exception handling since it helps in reduction of clutter in the handling code.
String used in Switch case- Before Java 7, String could not be used in case or Switch statement. Now with the addition of Strings the switch instruction has become much friendlier. Previously the alternative was to use else/if/else if statements which had to be paired with string.equals calls. The alternative implemented now has resulted in a more compact and cleaner code.
Automatic resource management- Generally a developer closes resources like input/outstreams, files, connections, etc manually through bog-standard codes. However, with this version the resources can be managed automatically. The operation is quite simple too; just the resources have to be declared.
Type inference through Diamond operator <>- With the introduction of Generics, programmers had to face a couple of tough challenges- its verbose nature and that duplicate code was generated. With the feature called Diamond operator <> introduced in Java 7, type inference is provided when Generic classes’ object is created. This method is very easy for that purpose and is far better than the Factory method creation.
Invokedynamic, for support of non-Java languages- Invokedynamic is a bytecode that has been newly introduced. This feature has an exciting part; improved support is provided for compiling programs where dynamic typing is used. Dynamically typed languages such as bash scripts, Ruby, etc as well as statically typed ones like Java need such instructions for the support of these kinds of variables. Many kinds of languages that are not Java based are supported by JVM. However, with the support of this instruction, the JVM becomes more language independent. This acts as great news for those who love implementing components in various languages or want interoperability between the standard Java programs and those languages.
Fork Join framework- The existence of Fork join framework has been as an individual JSR even before the particular version of the language came into existence. Now the version has got an additional feature in the form of this framework and it has become a part of its standard core library. By virtue of this framework, developers will be able to write codes by taking benefit of multiple cores that are available in modern servers.
Improved version of File IO API- Java.nio package has gone through many changes and finally a new package has emerged known as java.nio.file. This package has several interfaces as well as classes like Paths, Path, FileSystems, FileSystem, etc. The new classes have helped improve a developer’s life when he or she attempts to work with several file systems. Static methods are also provided for operations which are file related; like an entire file can be read very easily through readAllLines. Symbolic links can be created as well by this class. Another important feature is the setting of file permissions for file systems that are POSIX compliant.
Looking at the list of features that Java 7 has, it leaves no doubts as to why it has become so popular among developers over the other versions. Moreover these are only a few of the most popular features. There are several more features which have made software development a much easier action.
