What is the Java equivalent of Objective-C's NSDictionary?
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.

Calling C++ functions from Java

Closed 8 years ago.
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.
