What are the Signature lines of a Java class code?

With an example. and the UML diagram.

Expert Solution

Ans - A signature is a list that specifies a class constructor, an instance method, or a static method, thereby distinguishing it from other constructors, instance methods, or static methods.

The UML Class diagram is a graphical notation used to construct and visualize object oriented systems. A class diagram in the Unified Modeling Language (UML) is a type of static structure diagram that describes the structure of a system by showing the system's:

classes,
their attributes,
operations (or methods),
and the relationships among objects.

Example -

ATMs system is very simple as customers need to press some buttons to receive cash. However, there are multiple security layers that any ATM system needs to pass. This helps to prevent fraud and provide cash or need details to banking customers.
