1. Design ideas:
First, starting with the Javaapparguments.java example, this example has printed parameters that define the number
The sum and the integer type as the storage unit, then converts the string of the input parameter into an integer and then sums it.
2. Program Source code:
//Course Assignments//Li Hui, 2016.9.20 Packagedemo; Public classCommandparametersum { Public Static voidMain (string[] args) {//TODO auto-generated Method StubSystem.out.println ("Number of parameters:" +args.length); intsum = 0;//define the sum of numbers intNum;//as a storage unit for(String Arg:args) {Num=integer.parseint (ARG);//convert strings to numbersSum+=num;//The sum of numbers} System.out.println ("Sum of the Numbers:" +sum);//Output }}
3. Results:
Course Assignment 01: Imitate the Javaapparguments.java example, write a program that receives multiple numbers from the command line, and then outputs the result after summing.
