Example of using Scanner class in java

import java.util.*;

/*
 * java ScannerTest2 10 20 30 40
 * Count = 4
 * Total = 100
 * Avg = 25
 */
public class ScannerTest2 {
public static void main(String[] args) {
if(args.length<1){
System.exit(0);
}

String str ="";
for(int i=0;i<args.length;i++){
str = str+args[i]+ " ";
}

Scanner in = new Scanner(str);
int i=0, tot=0;
while(in.hasNextInt()){
i++;
tot += in.nextInt();
}

System.out.println("Count = "+i);
System.out.println("Total = "+tot);
System.out.println("Avg = "+tot/i);

}
