Using Scanner to compute an average of the values
Code:
import java.util.*; public class AvgNums { public static void main(String args[]) { Scanner conin = new Scanner(System.in); int count = 0; double sum = 0.0; System.out.println("Enter numbers to average."); // Read and sum numbers. while(conin.hasNext()) { if(conin.hasNextDouble()) { sum += conin.nextDouble(); count++; } else { String str = conin.next(); if(str.equals("done")) break; else { System.out.println("Data format error."); return; } } } System.out.println("Average is " + sum / count); } }
