Answer:

False

Explanation:

While Math.random() can be used to generate a random number, Java programming language also has a class called Random in the java.util package which can be imported into your code. This is a more efficient way of generating random numbers (ints or doubles) as you can instantiate several random number generators. The following line of code creates an an object of the class Random and sets the bound to 10.

Random rand = new Random (10);

This will generate random number from 0-9.

(a)

(I) The level of the given relationship is 2 i.e it is a parallel connection among Book and Publisher. It is a one to numerous relationship from distributer to book in light of the fact that a distributer can distribute any number of books however a book will have only one publisher,so the cardinality will be 1 to 1..* (one to many)

(b)

(i) The degree of the given relationship is 2 i.e it is a binary relationship between Author and Book. It is a many to many relationship from Book to Author a book can be written by one or more authors and an author can write more than one book, so the cardinality will be 1..* to 1..* (many to many)

(c)

(i) As mentioned in part (b), the degree of given relation is 2 and cardinality is many to many (1..* to 1..*)

(d)

(i) The degree of the given relationship is 1 i.e unary relationship. It is a many to many relationship because one book can belong to any sets and a set can have any number of books, so cardinality is 1..* to 1..* (many to many)
