Java memory overflow and java Overflow

1. What memory overflow exceptions are there?

OutOfMemoryError:
When the data capacity reaches the maximum value for the heap, stack (multi-thread scenario), method zone (permanent zone), and local memory (metadata and Direct Memory ),
StackOverFlowError:
The stack depth requested by the thread is greater than the maximum depth allowed by the VM stack (1 MB by default ).

Ii. What are the causes and solutions for heap overflow?

Cause:
An OutOfMemory exception occurs when the number of objects in the heap reaches the maximum capacity.
Solution:
-XX: + HeapDumpOnOutOfMemoryError can cause memory overflow on the Java Virtual Machine,
Generate a snapshot of the current heap memory for exception analysis. This mainly analyzes which objects occupy the memory.
