![]() In the next section, we'll look at some code examples that demonstrate these scenarios. This will cause the constructor of the same class to be called again and again (recursively) which eventually results in a StackOverflowError. This can also be considered as a form of recursion.Īnother interesting scenario that causes this error is if a class is being instantiated within the same class as an instance variable of that class. In this situation, the constructors of each other are getting called repetitively which causes this error to be thrown. Presumably users would declare their stacks using the interface type, for example: Stack strings new ArrayListStack<> () The stack of strings may get passed to methods expecting a Stack, and then if top or pop get called when the stack is empty, the.The StackOverflowError can also be thrown when an application is designed to have c yclic relationships between classes. ArrayListStack is an implementation of your custom interface Stack. Another rare cause is having a vast number of local variables inside a method. This is a rare case since no developer would intentionally follow bad coding practices. In linked list implementation, a stack is a pointer to the head of the list where pushing and popping items happens, with perhaps a counter to keep track of the listâs size. ![]() It can also happen in a situation where an application keeps calling methods from within methods until the stack is exhausted. However, recursion is not the only cause for this error. UPDATE: In order to apply element swapping, obviously the Node s involved MUST be a part of the list, otherwise there is no meaning in this. ![]() The logic behind this is simple: get the next node till the iteration cycles number reaches the index number. The most common cause for the JVM to encounter this situation is unterminated/infinite recursion â the Javadoc description for StackOverflowError mentions that the error is thrown as a result of too deep recursion in a particular code snippet. In fact, the LinkedList collection standard API in Java has such a method. ![]()
