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( )。
