java使用命令行參數輸入任意三個數？

public class ABC { public static void main(String[] args)

{double num1 = Double.parseDouble(args[0]);

double num2 = Double.parseDouble(args[1]);

double num3 = Double.parseDouble(args[3]);

double max = num1;

double min = num1;

if(num2 > max){ max = num2; }else{ min = num2; } if(num3 > max){ max = num3; }else{ min = num3; }
