有以下程序源代码public class TestException{ public static double calculateArea(double a, double b, double c) { double p = (a+b+c)/2; return Math.sqrt(p*(p-a)*(p-b)*(p-c)); } public static void main(String[] args) { double a = Double.parseDouble(args[0]);double b = Double.parseDouble(args[1]); double c = Double.parseDouble(args[2]); double s = calculateArea(a, b, c);System.out.println("边长为"+a+","+b+","+c+"的三角形面积是"+s); }}编译源程序之后,如果运行命令是java TestException 3 a.4,则系统会报出( )。
