🟡 MathExamples.java

Description This program demonstrates common Math class methods: abs, sqrt, pow, max, random, and ceil. It also includes a note on how to convert degrees to radians for trig functions. There are no user inputs; each method is called with hardcoded values to show its behavior. The outputs are the results of each Math method printed to the console.

package exam1problems;

public class MathExamples {

	public static void main(String[] args) {
		// TODO Auto-generated method stub

		System.out.println("Absolute: "      + Math.abs(-10)); //finding the absolute value of an int

        System.out.println("Square Root: "   + Math.sqrt(25)); //finding the square root of an int

        System.out.println("Power: "         + Math.pow(3, 4)); //this is three to the power of 4

        System.out.println("Max: "           + Math.max(8, 15)); //set a max

        System.out.println("Random (0-1): "  + Math.random()); //generate a random number

        System.out.println("Ceil: " + Math.ceil(2.5)); //rounds up, FLOOR ROUNDS DOWN

        //Remember for trig it is like these formats and that numbers must be in radians

        //IN ORDER TO GET RADIAN DO THIS EQUATION
        //radians = degrees * (Math.PI / 180)
	}
