The `random()`

method in the `Math`

class returns a random number between 0.0 and 1.0, including 0.0 and not including 1.0, at random with uniform distribution from this range. This method is written like `Math.random()`

and does not take in any parameters. The returns a `double`

value. Run the program below to see the function. As you may suspect, you will get different numbers every time you run the program.

```
package exlcode;
public class RandomMethodExample {
// Returns double value greater than or equal to 0.0 and less than 1.0
public static double exampleVariableOne = Math.random();
// Returns an integer value between 1 and 100
public static int exampleVariableTwo = (int) (Math.random() * 101);
public static void main(String[] args) {
System.out.println(exampleVariableOne);
System.out.println(exampleVariableTwo);
}
}
```

In order to increase our range from 0.0 to 100.0, we have to multiply the whole expression by 101 since the function's range is only 0.0 to 1.0. We then use casting to change the `double`

to an `int`

datatype value, which in turn truncates the decimal and gives us a whole number. There are different methods within the `Random`

class which may be useful to you for various projects in the future.
