Random number - Practice Exercises Java

Lesson 7:

Exercise 7.8:

Random number


Create a class RandomNumber, with three static methods:

- GetFloat will return a number between 0 and 1 using the following algorithm:

seed = (seed * a + c) % m
result = abs(seed / m)

- GetInt(max) will return a number from 0 to max, using:
result = round(max * GetFloat)

- GetInt(min, max) will return a number from min to max (you must create this one totally on your own).

The starting values must be:
m = 233280;
a = 9301;
c = 49297;
seed = 1;

Source Code:

package Random;
public class RandomNumber
	private static int m = 233280;
	private static int a = 9301;
	private static int c = 49297;
	private static int seed = 1;

	public static float GetFloat()
		seed = (seed * a + c) % m;
		return Math.abs(seed / m);

	public static int GetInt(int max)
		return 0;

	public static int GetInt(int min, int max)
		return 0;
