What is UML Diagram?
Unified Modeling Language (UML)
Standardized general-purpose modeling language
in the field ofobject-oriented softwareengineering.
The standard is managed, and was created, by the
Object Management Group.

UML 2.2 has 14 types of diagrams divided
into two categories.
Seven diagram types represent structural
information.
Seven represent general types of behavior.

What is class diagram?
Is a type ofstatic structure diagram that
describes the structure of a system by showing
the system's classes, theirattributes, operations
(ormethods), and the relationships among theclasses.

+ main(String[]):
void
Person
# name: String
# address: String
# setName(String): void
# setAddress(String): void
# getName(): String
# getAddress(): String
Student
- campus : String
# setCampus(String): void
# getCampus(): String
Employee
# totalSalary: double
# setTotalSalary(double): void
# calculateSalary(): void
# getTotalSalary(): double
Monthly
- numberOfAbsent : int
- salaryPerMonth : double
+ calculateSalary(): void+ addAbsent(int): void
Hourly
- salaryPerHour : double
+ calculateSalary(): void
+ addHour(float): void
