有如下程序： public class MethLoad { public static void main(String args[]) { MethLoad classObj = new MethLoad(); classObj.methtest(4); classObj.methtest(4.0); } void methtest(double D) { double sum = 2*d; System.out.println( The result is: +sum); } void methtest(int n) { int sum = 4*n; System.out.println( The result is: +sum); } } 程序的运行结果为( )。
A．The result is:16 The result is:8.0
B．The result is:8.0 The resuR is:16
C．The result is:8 The result is:16.0
D．The resuR is:16.0 The result is:8
