The unified modeling language (UML) is a general-purpose visual modeling language that is intended to provide a standard way to visualize the design of a system.
The static variables and methods are stored in the heap memory. In fact, all static methods are stored in the Heap memory.
Before the Java 8 version, static variables of the class were stored in a separate section of the non-heap memory named Method Area created by the Java Virtual Machine after the class compilation. Method area section was used to store static variables of the class, metadata of the class, etc. Whereas, non-static methods and variables were stored in the heap memory.
Cohesion in Java is the Object-Oriented principle most closely associated with making sure that a class is designed with a single, well-focused purpose. In object-oriented design, cohesion refers to how a single class is designed.
