Enter a few numbers at the command prompt, sum (flow chart I was sent in the form of a picture)

Program Design Ideas:

After visiting Baidu and other websites, I learned to convert the string s to an integer usable integer.parseint (s), so I knew how to translate the characters into integers. Enter multiple integers by a[i]=integer.parseint (Args[i]). Defines an array to receive numbers converted from characters, and finally sums them with a for loop.

Flow chart:

Program code:

public class add{

public static void Main (String args[]) {

int i,sum=0;

String c= "parameters are:";

String b= "sum is:";

Int[] A=new int[20];

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

System.out.println (c);

for (String Arg:args) {

System.out.println (ARG);

}

for (i=0;i<args.length;i++) {

A[i]=integer.parseint (Args[i]);

Sum=sum+a[i];

}

System.out.println (b+sum);

}

}
