Thread: Objects and Classes

I am just trying to figure out basic classes/objects. I am trying to write a program where it will return the area of a triangle. I realize this can be done easier another way but I am just trying to figure out how these things work....

import java.util.Scanner;
 
class Triangle {
	double height;
	double base;
 
	double getArea() {
		return 1/2 * height * base;
	}
}
 
public class study {
	public static void main(String[]args) {
		Triangle Triangle = new Triangle();
		Scanner in = new Scanner(System.in);
		System.out.println("Height?");
		Triangle.height = in.nextInt();
		System.out.println("Base?");
		Triangle.base = in.nextInt();
		Triangle.getArea();
		System.out.println("The area of a triangle with height " + Triangle.height + " and base " + Triangle.base + " is " + Triangle.getArea()); 
	}	
}

It keeps printing the null value 0.0 for area of a triangle.

try "return (0.5 * height * base);" instead of "return 1/2 * height * base;" It may be the 1/2 vs. 0.5

That worked. Thank you. Can't believe it was that simple.
