Java casts a numeric string into an integer variable----parameter and experiment code

Experiment Code:

Package demo;

public class CommandParameter {

/**
* @param args
* /
Public static void Main (string[] args) {
//TODO auto-generated method stub
int sum=0; //Set value initial value and 0
System.out.println ("Number of parameters" +args.length); //Length of output parameter number
For (String Arg:args) {

System.out.println (ARG); Use loop structure to output parameters
Sum=sum+integer.parseint (ARG); //cast a numeric string into an integer variable and add sums using the loop structure
}
System.out.println ("Sum of Parameters:" +sum); //The sum of the parameters is output

}

}
