What is StackOverflowError in Java ? When it occurs? [closed]

Question

Can anybody tell me what is StackOverflowError in Java ?

Answer 1

A stack overflow occurs when too much data is put on the stack, which is a limited resource.

Here's an example:

public class Overflow {
    public static final void main(String[] args) {
        main(args);
    }
}

That function calls itself repeatedly with no termination condition. Consequently, the stack fills up because each call has to push a return address on the stack, but the return addresses are never popped off the stack because the function never returns, it just keeps calling itself.
