hi friend,
import java.io.*;
import java.io.IOException;
import java.util.*;
public class StudentInfor{
//public static void main(String args[]) throws IOException{
public static void main(String[] args) throws IOException {
BufferedReader buff = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Student Information example");
Scanner input = new Scanner(System.in);
//... These variables hold the max and min incomes.
double maxnum = Double.MIN_VALUE;
double minnum = Double.MAX_VALUE;
int count = 0;
double totalIncome = 0;
//... Loop until negative number is entered.
System.out.println("Enter student number.");
while (input.hasNextDouble()) {
//... Get the next value.
double dou = input.nextDouble();
//... Compare this value to max and min. Replace if needed.
if (dou > maxnum) {
maxnum = dou;
}
if (dou < minnum) {
minnum = dou;
}
//... Keep track of these values for average calculation.
count++;
totalIncome += dou;
}
if (count > 0) {
double average = totalIncome/ count;
System.out.println("Number of values = " + count);
System.out.println("Maximum = " + maxnum);
System.out.println("Minimum = " + minnum);
System.out.println("Average = " + average);
} else {
System.out.println("Error: You entered no data!");
}
}
}
