Java Static Methods

What Makes a Method Static?

A static method belongs to the class itself rather than to any specific object, and can be called directly using the class name without creating an instance.

public static int square(int n) {
    return n * n;
}
// called as: MathUtils.square(5);

When to Use Static Methods

Static methods are ideal for utility/helper functions that don't depend on instance-specific data — for example, a helper method that formats a date or builds a common request header.
