You might need to increase the Java Heap Memory https://www.mathworks.com/help/matlab/matlab_external/java-heap-memory-preferences.html -- but if you are receiving the error as soon as you open MATLAB then changing the heap size might not help.
Do you happen to have a startup.m in your path that might be running some function ?

Hi Shikha,
This error can occur when the Java Garbage Collector has exceeded its overhead limit.
You can eliminate this error by following the workarounds mentioned below:
1. To disable the overhead limit, add the following line to the java.opts file:
-XX:-UseGCOverheadLimit
If a java.opts file already exists on your MATLAB path, add the above-mentioned line to this file. If the file does not currently exist on your machine, please create a text file called java.opts and place this file in the location:
$MATLABROOT/bin/$ARCH
where $MATLABROOT is the MATLAB root directory obtained by typing the following at the MATLAB Command Prompt:
matlabroot
and $ARCH is the output of typing the following at the MATLAB Command Prompt:
computer('arch')
2. One may force more Java garbage collection from the command line as well:-
r = java.lang.Runtime.getRuntime();
r.gc;
r.gc;
r.gc;
Running r.gc only once may not activate the object method and hence may need to be used more number of times.
Hope this helps!!
