Local variable and instance variable

This content originally appeared on DEV Community and was authored by KIRUBAGARAN .K

Local variables and instance variables differ primarily in their scope, lifetime, and storage location.

Scope
Local variables are declared within a method, constructor, or block of code. Their scope is limited to that specific block, meaning they are only accessible within the code block where they are defined.

Lifetime
The lifetime of a local variable begins when its declaring block is entered and ends when that block is exited. They are created and destroyed with each invocation of the method or execution of the block.

Storage
Local variables are typically stored on the stack memory.

Initialization
Local variables do not have default values and must be explicitly initialized before use.
