Question

32) Write a valid Java statement that generates a random value between 1 and 100, inclusive, and assigns that value to randPer.

33) What library must be imported to use the Java random number generator class and its methods? Give the correct import statement needed to ensure that this class is available for use in the program using it.

34) Write a valid method in Java that performs a simulated coin-toss – meaning it returns boolean value of either true or false based upon use of the Java random number generator. You may assume the instance of the generator was created elsewhere, and is named coin.

35) Write examples of an integer constant, a floating-point constant and a string constant in Java, where each of these is a static member of the class it is declared in.

Answer 1

32.

we can use eg:- r.nextInt(101)

For a more generic "in between two numbers" use:

program:-

This gives you a random number in between 0 (inclusive) and 100 (exclusive)
