I come up an idea to read a byte[] array with the same size of the input, and check one by one. But it seems not very efficient. Is there a way to solve it by using rolling hash?
If you are using java 8 or above please check the
java.util.Optional<T>
The documentation is here
Optional

Calling C++ functions from Java

Is there a way to insert some c++ code in java ?
for some reason my code which is:
ArRobotPacket pkt;
pkt.setID(ArCommands::SIM_SET_POSE);
pkt.uByteToBuf(0); // argument type: ignored.
pkt.byte4ToBuf(x);
pkt.byte4ToBuf(y);
pkt.byte4ToBuf(th);
pkt.finalizePacket();
robot.getDeviceConnection()->write(pkt.getBuf(), pkt.getLength());
translated to java, will not function, the write will actually send a packet but doesn't effect the program the way it should
This code is from
http://robots.mobilerobots.com/MobileSim/download/current/README.html#mapobjs
One way is to use Java Native Interface: http://docs.oracle.com/javase/6/docs/technotes/guides/jni/

As i have experience in iOS and newbie to Android development, i wqant to implement grouped tableview in Android.
Can anyone tell me what is the replacement of NSDictionary in android...
Many thanks in advance
NSDictionary is just a dictionary type; in Java these are called "Maps" instead. You can use any Map implementation to do the same thing, of which the normal "default choice" is HashMap.

I've seen other answers but they seem to squabble over each other in terms of response.
I need to translate some Objective-C and I am using NSDictionary a lot. What should I try to use in Java for this ?
The best Java equivalent is a Map implementation specifically HashMap.
