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

Source: Internet
Author: User

Design idea: First we get the parameters from the command line, because we get the parameter is the form of the string, so we need to convert it to a number form, then we can add the parameters to calculate the final result

Program Flowchart:

Program source code:Package lianxi2;
Import java.util.*;
public class Javaapparguments
{
public static void Main (string[] args)
{
Double number=0;
for (String Arg:args)
{
Double number1 = Integer.parseint (ARG); Get a parameter from the command line and convert it to a number and assign it to Number1
Number=number+number1; Number and Number1 add
}
SYSTEM.OUT.PRINTLN ("Add Result:" +number); Output results
}
}

Results:

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