  Scanner input = new Scanner(System.in);
  //Declare variables
  double base1, height1, base2, height2;
  //Prompt user for inputs
  System.out.println("Provide values for the base and height of the two triangles");
  System.out.print("Base of Triangle 1: ");
  base1 = input.nextDouble();
  System.out.print("Height of Triangle 1: ");
  height1 = input.nextDouble();
  System.out.print("Base of Triangle 2: ");
  base2 = input.nextDouble();
  System.out.print("Height of Triangle 2: ");
  height2 = input.nextDouble();
  //Compare and Print Results
  if(0.5 *base1 * height1 > 0.5 * base2 * height2)
  {
  	System.out.print("Triangle with larger area: Base: "+base1+" Height: "+height1+" Area: "+(0.5 * base1 * height1));
  }
  else
  {
  	System.out.print("Triangle with larger area: Base: "+base2+" Height: "+height2+" Area: "+(0.5 * base2 * height2));
  }
 }
