Analog/Digital data usage in java

Question

Is there a way in java to get the input from say a proximity sensor which gives out analog/digital data and display it on the screen.

If it does take analog/dital inputs how does one sync a hardware device such as a proximity sensor and java.

Just researching at this this stage.

If there is a way for java to function with this off beat devices and use this kind of data in our applications.

Java can use anything which is available to the OS. If you have an OS driver which makes your device look like a file system or serial device, you can access it from Java. i.e. the real issue is between your device, your machine and your OS. ....

As @Peter already mentioned, it's all about the API and whether you can integrate it into the Java runtime (keep in mind that you can access native APIs via JNI, etc.). You have to assess each sensor regarding its integration capabilities. — home, Aug 04 '12 at 10:52

Thanks peter.Say if I were to buy a proximity sensor now, then on what factors should i focus on so that i could integrate this with a java program. – gautam vegeta Aug 04 '12 at 11:10
Does the proximity detector say it can be integrated with Java? If not does their support suggest how it can be used with Java? – Peter Lawrey Aug 04 '12 at 11:27
Thanks for the info.I'll get back after i collect all the relevant details. – gautam vegeta Aug 04 '12 at 12:58
