In Java, memory management is crucial for efficient program execution. There are two primary types of memory: stack memory and heap memory.
Stack Memory: Stack memory is used for managing method calls and storing local variables with fixed lifetimes. It follows a last-in-first-out (LIFO) structure, and memory allocations are efficient. Static variables like integers and references to objects can be allocated here. Method calls and local variables are also managed in stack memory.
Heap Memory: Heap memory is a separate region used for dynamic memory allocation. It’s where objects and arrays with varying lifetimes reside. Memory in the heap is managed by a garbage collector, which automatically reclaims memory from objects no longer in use, preventing memory leaks. Objects like strings and arrays are typically allocated in heap memory. For instance, when you create an object or an array using the ‘new’ keyword, it’s allocated in heap memory
What is “Memory Leak”?
It occurs when it unintentionally retains and consumes memory that is no longer needed or referenced. Over time, these accumulated memory leaks can lead to the exhaustion of available memory resources, causing the program to slow down or eventually crash due to insufficient memory. Memory leaks are a common…
