Declared Static
TLDR: When a method, variable, or block is declared `static` in programming languages like Java or CPP, it means the member belongs to the class rather than any specific instance of the class. Declaring static members as `static` enables shared access across all objects of the class, making it ideal for utility functions or shared constants. Static members are resolved at compile time, enhancing performance and predictability.

A `static` method in Java or CPP can be called directly using the class name without creating an instance of the class. For example, `Math.pow()` in Java is a `static` method used to calculate powers. Similarly, `static` variables retain their value across multiple invocations and are initialized only once. Declaring members as `static` simplifies code by avoiding the need for object creation when shared functionality or data is required.

While `static` declarations improve memory efficiency and access performance, they have limitations. Static methods cannot access non-static members of the class directly because they lack a reference to any specific instance. Overriding `static` methods is also not possible; instead, the concept of method hiding applies. Proper use of `static` declarations ensures clarity, efficiency, and appropriate scoping in program design.
