Java Math class has many methods that allow you to perform mathematical operations.


example:

public class JavaApplication {

    public static void main(String[] args) {

        Math.max(15, 2); //get the max value : 15
        Math.min(5, 20); //get min value : 5
        Math.sqrt(12); //get the square root: 3.46
        Math.abs(-8.7); // absolute (positive) value: 8.7
        Math.random(); // returns a random number : 0.10

    }

}
