Answer 1

The following program will count the number of chacters entered until Z is enetered.
import java.io.*;
class count
     public static void main(String[] args)throws IOException
          char ch;
          int cnt=0;
          DataInputStream br=new DataInputStream(System.in);
          do
          System.out.print("Enter a character:");
          ch=(char)br.read();
          if(ch!='Z')
               cnt++;
          else
               break;
          }while((ch=(char)br.read())!='Z');
          System.out.println("The Number of entered characters are:"+cnt);
}
