Math class and its different methods

Java math class consists of arithmetic math methods that performs basic numeric operations such as finding the maximum or minimum of two values, rounding values, logarithmic functions, square root, and trigonometric functions, etc. The Math library functions can be accessed using the header Java.lang.Math. These math methods under Java math class are for our convenience.

Question

domly selects an object from the box and returns it. If the user attempts to drawn an item out of an
empty box, return null. Write a main method that tests your class.
The following is a short snippet of code that simulates rolling a 6-sided dice 100 times. There is an equal chance of
rolling any digit from 1 to 6.
public static void printDiceRolls(Random randGenerator)
ii.
for ( int i-0; i< 100; i++)
System.out.println(randGenerator.nextInt(6) + 1);
public static void main(String] args)
Random randGenerator = new Random();
printDiceRolls(randGenerator);
Create your own class, LoadedDice, that is derived from Random. The constructor for LoadedDice needs to only
invoke Random 's constructor. Override the public int nextInt(int num) method so that with a 50% chance, your
new method always returns the largest number possible (i.e., num - 1), and with a 50% chance, it returns what
Random's nextInt method would return.
Test your class by replacing the main method with the following:
LoadedDice myDice = new LoadedDice();
printDiceRolls(myDice); You do not need to change the printDiceRolls method even though it takes a parameter of
type Random. Polymorphism tells Java to invoke LoadedDice 's nextInt() method instead of Random 's nextInt()
method.
