Java Development Kit / Java Software Development Kit (JDK / JSDK)

The Java Development Kit (JDK) is an Oracle Corporation product aimed at Java developers. Since the introduction of Java, it has been by far the most widely used Java Software Development Kit (SDK).

The JDK has as its primary components a collection of programming tools, including:

java – the loader for Java applications. This tool is an interpreter and can interpret the class files generated by the javac compiler. Now a single launcher is used for both development and deployment. The old deployment launcher, jre, no longer comes with Sun JDK, and instead it has been replaced by this new java loader.

WhatsApp Launches Voice Messaging Known as Push-To-Talk Service in its latest Update

With all the texting that people do these days, it’s naturally taken a messaging app to re-introduce the act of using our voices to communicate.

WhatsApp, the increasingly ubiquitous global messaging app, has launched “voice messaging,” a new feature that will let users record and send audio files with one tap on their smartphones. UPDATE: WhatsApp has announced the feature on its blog; the post includes a video demo, also embedded below.

The messaging company, which has 45 employees and is based in Mountain View, Calif., confirmed a report in AllThingsD that the service would allow users to press and hold the microphone on their keyboard to send a voice message, a bit like using a walkie-talkie.

Said to be a brainchild of the US-based company's co-founder and CEO Jan Koum, the new feature allows users to just hold to record a message and release to send it.

There is also a blue blinker notification that lets users know when the message is received. In case the user decides not to send the message, a swipe to the left and the recording is deleted. All this is built into a single tap. There is also no time-length limit for the recorded messages. Also, the volume automatically switches from speaker when held at arm's length to soft when held next to an ear.
