Generating Random Numbers in Java

//What is the range that this call will generate?

System.out.println(Math.random());

[0, 1)

/**Suppose n is a correctly instantiated int variable

* What is the range that this call will generate?

*/System.out.println(Math.random() * n);

[0, n)

/**Suppose n is a correctly instantiated int variable

* What is the range that this call will generate?

*/

System.out.println(Math.random() + n);

[0 + n, 1 + n)

/**Suppose max and min are correctly instantiated int variables

* What is the range that this call will generate?

*/

System.out.println((Math.random()*(max - min)) + min);

[min, max)

/**What is the range that this call will generate?

* Pay attention to the casting call!

*/

System.out.println((int)(Math.random());

0

**Suppose n is a correctly instantiated int variable

* What is the range that this call will generate?

* Careful with the casting call!

*/

System.out.println((int)(Math.random() * n);

All integers from [0,n)

/**Suppose n is a correctly instantiated int variable

* What is the range that this call will generate?

* Careful with the casting call!

*/

System.out.println((int)(Math.random()) + n);

Every integer from [0 + n, 1 + n)

/**Suppose max and min are correctly instantiated int variables—

* What is the range that this call will generate?

* Careful with the casting call!

*/

System.out.println((int)(Math.random()*(max - min)) + min);

Every integer from [min, max)

What statement would you use to generate a random number from a minimum value, to a maximum value—exclusive?

(Math.random()*(max - min)) + min

What statement would you use to generate a random number from a minimum value, to a maximum value—inclusive?

(Math.random()*((max + 1) - min)) + min
