Study Notes
What is an Object?
- Objects are essential for dynamic memory allocation, allowing software to reserve or release space based on application requirements.
- Static members are loaded into memory prior to execution, making them unsuitable for dynamic data handling during runtime.
- The
public static void main(...)
indicates that the main method's bytecode is loaded first in RAM. - Static members maintain a single memory location; hence, they can only hold one value at a time within the class context.
- Resetting a static value does not change its memory location.
Pseudocode and Flowcharts with Objects
- Use special 'box' icons to represent external processes in pseudocode and flowcharts involving objects.
- Objects can be declared or manipulated later using setters like regular methods.
- Utility classes, such as Math, utilize static methods to perform operations without needing object instances.
- Static variables are necessary for shared data across instances, such as tracking the number of created objects.
- Declaring constants as
static final
optimizes memory usage by avoiding duplication with every object instance.
Garbage Collection
- Memory management is critical; objects should be deleted once they are no longer required.
- Early object-oriented programming languages, like C++, required manual memory management.
- Modern languages, such as Java, implement garbage collection to automatically free up memory occupied by unused objects.
