Chapter 5.1, Problem 5SCP

Explanation of Solution

Range of value for “a” variable:

Given statement:

//create an object for "Random" class

Random rand= new Random() ;

/*declare the variable and generate the random number*/

int a = rand.nextInt(100);

Explanation:

• Create an object “rand” for the “Random” class.
• Declare the integer variable “a” and generate the random number between 0 through 99 inclusive.

Therefore, the variable “a” has 0 through 99 inclusive.

Range of value for “b” variable:

Given statement:

//create an object for "Random" class

Random rand= new Random() ;

/*declare the variable and generate the random number*/

int b = rand.nextInt(20) + 50;

Explanation:

• Create an object “rand” for the “Random” class.
• Declare the integer variable “b” and generate the random number between 50 through 69 inclusive.

Therefore, the variable “b” has 50 through 69 inclusive.

Range of value for “c” variable:

Given statement:

//create an object for "Random" class

Random rand= new Random() ;

/*declare the variable and generate the random number*/

int c = rand.nextInt(20 + 50);

Explanation:

• Create an object “rand” for the “Random” class...
