Answer 1

StackOverflowError

• It is related to Stack memory.
• It occurs when Stack is full.
• It is thrown when you call a method and there is no space left in the stack.
• It occurs when you are calling a method recursively without proper terminating condition.
• How to avoid? Make sure that methods are finishing their execution and leaving the stack memory.

OutOfMemoryError

• It is related to heap memory.
• It occurs when heap is full.
• It is thrown when you create a new object and there is no space left in the heap.
• It occurs when you are creating lots of objects in the heap memory.
• How to avoid? Try to remove references to objects which you don’t need anymore.
