"Hi guys i'm Deepu.please refer the matlab code below. and i want to know why we are using jtcp ??And one more help need please explain below code,actually what these lines are? its my kind request"
dynamicJavaClassPath = javaclasspath('-dynamic');
for i=1:100
try
%i

My speculation is that the person who wrote the code did not want to rely on the Instrument Control Toolbox in the days before MATLAB made tcpclient() part of regular MATLAB, so they used Java instead.
The code opens a tcp connection to port 1066 on a host in a private network. Port 1066 has no standard program associated with it, so we can assume that the server is running a custom program.
