The code below shows the new approach to ‘catching’ exceptions in JDK 7 – two or more exceptions can be grouped in the same catch statement, provided that the error handling code treats the exception argument as the common supertype of the exceptions which are part of the catch statement. In Java 6 and previous versions only byte, char, short, int and enum constants (along with the Byte, Character, Short and Integer wrappers) are allowed as values for the cases, whereas JDK 7 adds support for String objects public void printDay(String dayOfWeek)Ĭase "Sunday": ("Dimanche") break Ĭase "Monday": ("Lundi") break Ĭase "Tuesday": ("Mardi") break Ĭase "Wednesday": ("Mercredi") break Ĭase "Thursday": ("Jeudi") break Ĭase "Friday": ("Vendredi") break Ĭase "Saturday": ("Samedi") break ĭefault: ("Error: '" + dayOfWeek + "' is not a day of the week") break The next example shows a simple usage of the switch statement containing a String as argument. We’d love to see your versions of the above code with that handling factored in, please do post in the comments or on our google group! The sharp eyed amongst you will also realise we haven’t dealt with the MalformedURLException either. The above code can be reduced down to: URL url = new URL(" ") Now as Alan Bateman (lead for the NIO.2 project) has kindly pointed out, the latest developer preview of JDK 7 (build130) makes the actual file I/O work much simpler. Try (FileOutputStream fos = new FileOutputStream(new File("output.txt"))
Notice that the TWR feature automatically handles closing of the FileOutputStream and InputStream resources. In the following example, the HTML content from an URL is read and written in a file. They reflect some of the changes from the new Java specification. You can go ahead and copy/paste the following code snippets directly in your IDE. Select “Sources” on the left side and make sure JDK 7 is selected under Source/Binary Format option.in Debian it’s under /usr/lib/jvm/jdk1.7.0 ), then click “Next”, type a platform name unless it is not automatically detected, then press “Finish” If not, click on “Manage Platforms” > “Add Platform” then navigate to the installation folder of the JDK (e.g. Select “Libraries” on the left side and make sure “JDK 1.7” is selected at the Java Platform option.Right-click on the project root and select “Properties”.
CONFIGURE NETBEANS JDK INSTALL
If you install JDK 7 after Netbeans you can follow the instructions below to configure Netbeans 7.0 Beta 2 with JDK 7. Should you have a recent JDK 7 build on your computer (from following our earlier blog post), then the installer will recognize it without any problems.
CONFIGURE NETBEANS JDK UPDATE
Beta 2 supports the latest JDK7 builds allowing you to try out the new JDK 7 features such as Project Coin:įor you bold explorers you can get further information on all of the JDK 7 features.ĭownload & Installation of Netbeans 7.0 Beta 2Ī full detailed description of installing, uninstalling and troubleshooting instructions for this version of NetBeans can be found on the official website.įirst and foremost navigate to the official download site, select your favourite IDE configuration and click on one of the “Download” buttons.īefore installing it, make sure you have at least JDK 6 installed (preferably update 24), as NetBeans IDE 7.0 Beta 2 cannot be installed using JDK 5.
Of course there’s one extra big reason to be cheerful with Beta 2 coming out, seamless JDK7 support. Happily we have good news on both of those fronts with the Ruby community stepping up to support the Netbeans Ruby plugin, and the Oracle engineers cleverly getting around the JUnit legal stoush by prompting you to immediately download and install JUnit upon starting Netbeans for the first time. Oracle has released NetBeans IDE 7.0 Beta 2! Some developers might be disappointed with the discontinuation of official Ruby support, or the fact that JUnit is no longer being bundled by default.
