How to calculate triangle area from command line inputs

TriangleArea

import java.util.Scanner;

class TriangleArea {
  public static void main(String[] args) {
    Scanner kb = new Scanner(System.in);
    
    System.out.println("This program will help you calculate the area of a triangle.");
    
    System.out.print("What's the height of the triangle? ");

    String heightText = kb.next();
    
    System.out.print("What's the base of the triangle? ");
    String baseText = kb.next();
    
    int height = Integer.parseInt(heightText);
    int base   = Integer.parseInt(baseText);
    
    double area = height * base / 2;
    
    System.out.println("Your area is: "+area);
  }
}
