Key Takeaways: Java Math

Mastering Java Math helps you write clean and reliable Java code. Follow standard conventions, test edge cases, and keep logic simple. Try running the code example below and complete the exercises to build confidence.

Java Math Code Example

Java

public class Main {
    public static void main(String[] args) {
        System.out.println(Math.max(5, 10));
        System.out.println(Math.sqrt(64));
        System.out.println(Math.pow(2, 10));
        System.out.println(Math.round(4.6));
        int dice = (int) (Math.random() * 6) + 1;
        System.out.println("Dice: " + dice);
    }
}
