Question

The UML models operations by listing the operation name followed by a set of ____. A plus sign (+) in front of the operation name indicates that the operation is a public one in the UML (i.e., a public method in Java).

Answer:

To properly answer this question, let us first define what a UML is:

UML can be defined as or is simply refereed to as Unified Modelling Language. It is considered as the standard for modeling language that enables designers and developers to specify, visualize, construct and document object or programs made by them in the areas of software systems, Thus, UML makes this objects developed by computer gurus secure and robust in execution.

If we now go back to the question asked while referencing the explanation given of what a UML is, the answer to the question is

parentheses.

However, if the original question being asked is valid, the answer to it would be : sign (+) in front of the operation name

Answer 2

In unified modeling language (UML) class diagrams, a positive sign (+), which is an access modifier indicates a public operation.

A unified modeling language (UML) can be defined as a standardized, general-purpose modeling language that utilizes both text and graphic documents to specify, construct, visualize and analyze the design of an object-oriented system.

In unified modeling language (UML), a class diagram is a graphical notation which describes and provides an overview and structure of an objected-oriented system by illustrating:

• Operations

• Attributes

• Relationships between classes.

Hence, a unified modeling language (UML) class diagram is typically used to summarize the attributes and operations of a class.

Furthermore, operations are modelled in unified modeling language (UML) by listing an access modifier, the operation name and then followed by a parenthesis (). For example, + myassignment () is a public operation in unified modeling language (UML) and a public method in Java.
