How many function calls will a stack overflow cause

Hi, android / java developers,

When a function calls a function, and this function calls another, etc., how many calls (stack length) will lead me to the stack through the stream? Is there a general rule?

The reason I ask is because I am now more efficient (design wise) for my 5-player card game.

Solution 1:

for(int i=0;i<100;i++){
         p1.play();
         p2.play();
         p3.play();
         p4.play();
}

Solution 2:

   p1.play();    //where p1.play() calls p2.play() and so on until p4 calls p1 again.   
                 // this will go on for 100 times

I prefer solution 2, so if there is a failure, I see all the function calls from p1 with i = 0 to p4 with i = 100

but with solution 1, the stack is much shorter, but when the crash occurs, I will see at the beginning of the loops the play () function being called where the crash occurred

What are you offering? I know that these are 2 questions in 1, but they are very related.

Thank you all
