Java stackoverflowerror what is the correct stack size to use?

I am running into Java StackOverFlowError upon running a recursive program. The program is correct and the recursion needs to be implemented. I tried to find the current stack size using the command 

    java -XX:+PrintFlagsFinal -version | grep ThreadStackSize

and this is what i got:

 intx CompilerThreadStackSize                   = 0                                   {pd product}
 intx ThreadStackSize                           = 1024                                {pd product}
 intx VMThreadStackSize                         = 1024                                {pd product}

java version "1.8.0_101" Java(TM) SE Runtime Environment (build 1.8.0_101-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.101-b13, mixed mode)

What does this mean? And how can I increase the stacksize and what value should i set? Is it normal to get this error for the above settings?Please help.

It means the stack size is 1MB (1024KB). And you can increase the thread stack size by passing -Xss<size>, for example to set the stack size to 32 MB for each thread:

java -Xss32m

Usually a stack size of 1MB is enough. For most of the projects I worked on, I rarely need to change the stack size. So quite possibly your code is not correct as you think.

If you are writing a recursive code and it doesn't have code to terminate the recursion then you will eventually get the stackoverflow error , no matter how much high is your stack size.

There is nothing which you can do apart from fixing your code, which causes this error.
