Question

The question requires you to have completed the Random program (page 13).

Modify the body of the getNumber method so it looks like the following.

return (int)(2+3*Math.random());

/ Output a random integer [0,91 and its square public class Random Class name (public static void main (String args) int numbergetNumber int result = squareNumber (number); show (number, result); Methods public static int getNumber f return (int) (10 java.lang.Math.random)) Class body public static int squareNumber (int number) return (int)Math.pow (number, 2); public static void show (int number, int result) t System.out.println ("Random Numberlt" +number"") System.out.println ("Number Squared " +result +"")

Explanation / Answer

The value of the random number generated by the updated program will be always 2, 3 or 4.

Since , the java.lang.Math.random() returns a double value with a positive sign, greater than or equal to 0.0 and less than 1.0.

if java.lang.Math.random() falls in range [0,1/3) then (int)(2+3*Math.random()) will be 2.

if java.lang.Math.random() equals 1/3 then (int)(2+3*Math.random()) will be 3.

if java.lang.Math.random() falls in range (1/3,1) then (int)(2+3*Math.random()) will be 4.
