Example:-

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class AvarageTest { public static void main(String[] args) throws IOException { System.out.println("Input any No."); BufferedReader br = new BufferedReader(new InputStreamReader(System.in)); String data = (String) br.readLine(); int num = Integer.parseInt(data); int sum = 0; float avg = 0.0f; for (int i = 1; i <= num; i++) { sum = sum + i; } avg = sum / num; System.out.println("Sum- " + sum); System.out.println("Avg- " + avg); } }

**Output**
