How To Generate a Random Number

The Math.random() method can be employed for generating random numbers.

Math.random() yields a random number ranging from 0.0 (inclusive) to 1.0 (exclusive).

Example

Math.random();

For greater control over the generated random number, such as limiting it to a range like 0 to 100, you can utilize the following formula:

Example

int randomNum = (int)(Math.random() * 101); // 0 to 100
