public class Main //define main class.
{
public static void main(String[] args)//define main function
{
Scanner scan=new Scanner(System.in); //creating object.
//print values.
System.out.print("Enter integers. Enter -1 to exit.");
System.out.println(" Count of integers entered will be returned.");
int n=0,c=0; //declaring integer variable.
while (n != -1) //loop
{
n = scan.nextInt(); //take input by user and hold on variable n.
c++;
}
System.out.println(c); //print value.
}
}
output:
Enter integers. Enter -1 to exit. Count of integers entered will be returned.
