Hello friends I encountered a problem i,e
Software/Hardware used:
eclipse
import java.io.*;
public class execute {
public static void main(String args[])throws Exception{
char cname;
BufferedReader br= new BufferedReader(new InputStreamReader(System.in));
System.out.println("enter a letter");
cname= (char)br.read();
if(cname==' '){
System.out.println("u entered a space");
}
else {
System.out.println("u entered a character");
}
