Title Requirements:

Imitation Javaapparguments.java example, write a program that receives multiple numbers from the command line and outputs the results after summing.

1, design ideas:

The sum is defined and the initial value is set to 0 , the number is represented by Arg.length, and the Sum=sum+integer is used. parseint (ARG) to achieve the sum of the numbers. The sum of the number and sum of the last output numbers. In addition, when running the program, run as Run configurations is required to make a number of inputs.

System. out. println ("Number of parameters" +args.length);

for (String Arg:args)

{

System. out. println (ARG);

Sum=sum+integer. parseint (ARG);

}

System. out. println ("The sum of parameters" +sum);

}
