Array is a data structure that stores a collection of elements of the same type.
Arrays have a fixed size, while tuples can have a variable size.
Arrays are mutable, meaning their elements can be changed, while tuples are immutable.
Example: ['apple', 'banana', 'cherry']
Function, dictionary, and tuple are data structures in Python.
Function is a block of code that only runs when it is called. It can accept parameters and return values.
Dictionary is a collection of key-value pairs. Keys are unique and immutable, while values can be of any data type.
Tuple is an ordered, immutable collection of elements. It is defined using parentheses.
Arrays have fixed size, while lists can dynamically grow. Arrays store elements of the same data type, while lists can store different data types.

Java uses automatic memory management through garbage collection to allocate and deallocate memory.
Java uses garbage collection to automatically manage memory by deallocating objects that are no longer needed.
The JVM has a heap where objects are allocated and garbage collection is performed to reclaim memory.
Java provides the 'finalize()' method for objects to perform cleanup before they are garbage collected.
Memory le...
Different types of garbage collection algorithms in software development.
Mark and Sweep: Identifies and removes unreachable objects.
Generational: Divides objects into different generations based on age.
Parallel: Uses multiple threads to perform garbage collection concurrently.
Incremental: Spreads garbage collection work over multiple cycles to reduce pause times.
