UML දන්න අය ඉන්නවද? ලොකු උදව්වක් ඕනා

1. මට UML වල Coupling and Cohesion කියන්නේ මොකක්ද කියල පැහැදිලි කරලා දෙනවද ?

2. method එකක් private or protected කරන්න ඇයි කියලා පැහැදිලි කරලා දෙනවද ?

3. what is meant by a class-wide (sometimes called static) attribute or method ?

Coupling and Cohesion
P | N Cohesion is the degree to which the responsibilities of a single component form a meaningful unit

Coupling describes the relationship between software components

Goal: Reduce coupling, increase cohesion

cohesion and coupling kiyanne module/function dekak kochchara durata independance da kiyala balana ekata. high coupling nam functional strenght eka adui. a kiyanne module ekata independant weda kirime hekiyawa adui.

Low Couplin and High Cohesion thamai hoda

private , protected, public kiyanne access modifiers . private methods acces karanna puluwan class eka athule witharai. Protected walin class eka athule and derived classes wala access karanna puluwan. public nam external classes walinuth method eka access karanna puluwan
