What's new in Java or JDK 7
It's been almost a year since JDK 7 or Java 7 was released, but the programmer asks what's new in Java 7? What is the best resource introduced in JDK7, where is the list of all the new Java 7 features, etc? I have thought about documenting the 5 main features introduced in Java 7 for easy reference, this will not only answer what's new in Java 7, but it will also provide a quick overview of what these features are in Java 7. Java 7 introduced Many new features of Java programming language such as trying to capture with a resource, String on the switch, etc., but also makes a lot of change in the Java development API, introducing the new API files in Java and other small changes. For example. Now you can find hidden files of the Java program without applying any hack. Anyway, let's see my list of the 5 main features of Java 7:
The 5 new new features of Java 7
Here are my Top 5 new favorite Java 7 features introduced in the Java programming language in version 7. There are many other features in Java 7 that are introduced along with these front line features, such as changes to the File API, that also deserve to be exploited
Allow to use chain in case of switching
You can not use String in Switch or case statement before Java 7. Talk about allowing String in the case of Switch was growing since Enum was introduced in Java 5, although you can use Enum in the case of Switch, you can not do what same with String which is more common than Enum in the Java programming language. of the JDK 7 you can use the String in Switch case, see How to use the String in Switch case in Java7 for more details.
Multiple Exception in a catch block
This is the first resource that comes in my mind when people ask What's new in the Java 7 resource? Can you cite some new features introduced in the release of JDK 7? From JDK 7, you can capture several Exceptions in a catch block. This is called the blocking feature of multiple Java 7 captures. This is a significant improvement of Java 7 made in the Exception handling because it will reduce the confusion in the Java Exceptions handling code. To learn how to capture several exceptions in the catch block once in Java 7, see this article. Explains this new feature of Java 7 beautifully.
Automatic management of resources or ARM blocks
Like the previous Java 7 function, automatic resource management (ARM blocks) also known as try with resource block is another significant improvement in the area of exception manipulation in Java. The ARM blocks allow the automatic closing of resources, for example Files, Flows, etc., opened within the try block. The functionality must implement the Closeable interface in Java. See how to use the ARM block in Java 7 for more details.
Fork binding structure in Java 7
Another new feature that you can use to answer the question of the Java interview What's new in Java 7? The fork binding framework exists even before Java 7, but as a separate JSR. It has been added as a new feature in Java 7 to be part of the standard Java 7 main library. The fork binding structure allows writing code that can take advantage of several cores present in modern servers. See How to use the bifurcated link structure in Java 7 for code example and guidance on the use of the fork joint structure.
Diamond operator <> for type inference
Since Java 5 introduced Generics in Java, programmers complain that they are very detailed and generate duplicate code, which is true because when creating a java parameterized class object you need to provide type parameters on the left and right side. The diamond operator <> is a new Java 7 feature that provides type inference when creating generic class objects. Although you can achieve type inference without using Java 7, by creating the Factory method in Java, the Diamond operator is an easy way to get type inference in Java 7.
This was my list of the 5 new new features introduced in Java 7 and now you can reply What's new in Java 7. These were some of the most popular new features of JDK 7. Many production systems are still running in several updates to JDK 6 But I guess they're also slowly updating to Java 7. Now, even talking about Java 8 is growing, because you can enter closures in Java, which was previously planned to be released in Java 7 along with these new ones resources.
