StackOverflowError到我在Java中的递归调用

Question

i'm getting StackOverflowError to my recursive call:

    Exception in thread "main" java.lang.StackOverflowError
        at Test.trailMngr(Test.java:112)
        at Test.trailMngr(Test.java:115)
        at Test.trailMngr(Test.java:115)
        at Test.trailMngr(Test.java:115)
        at Test.trailMngr(Test.java:115)
        ...
    Java Result: 1

Is there a way to fix this without changing the code?

The only way i can think of is making it a non-recursive method.

Everything else in the code is working fine in smaller input sizes-- i'll avoid the change if possible (although i'm not hopeful).

Not well-familiar with how Java behaves on these things.

TIA.

Assuming you're not dealing with infinite recursion, you can increase the stack size using the command-line Xss parameter:

java -Xss8m Test

This is the amount of memory allocated for every thread's internal use. Sizes can be specified in bytes ( -Xss8 ), kilobytes ( -Xss8k ), megabytes ( -Xss8m ) or gigabytes ( -Xss8g ). Note that setting this to a high value will obviously increase your memory usage.
