Can't Input Last Character; Program Ends Abruptly

import java.io.*;

public class Ascii {


public static void main(String[] args) {

TextReader UserInput = new TextReader(System.in);
System.out.println ("Please type the start character");
char startChar = UserInput.readChar();

System.out.println ("Please type the last character");
char lastChar = UserInput.readChar();

if (lastChar < startChar){
System.out.println ("Error, last character is before start character");
}

for (char ascii = startChar; ascii <= lastChar; ++ascii){

System.out.print (ascii);
}

} // end of main

} // end class


The output of the above code gives me the following:

Please type the start character
a
Please type the last character
Error, last character is before start character
Press any key to continue...

The program doesn't give me time to input the last character. Any suggestions?

Do you press return after entering the first character?

Try this........

Code:

---



 import java.io.*;

 public class A{
  public static void main(String[] args){
  try{
  BufferedReader buff = new BufferedReader(new InputStreamReader(System.in));
  System.out.println("Please enter your first character");
  String firstchar = buff.readLine();
  System.out.println("Please enter your last character");
  String lastchar = buff.readLine();

  char c1 = firstchar.charAt(0);
  char c2 = lastchar.charAt(0);
 
  if(c1 > c2){
  System.out.println("First char comes after second char");
  }else{
      System.out.println("First character comes before last char");
  }

  for (char ascii = c1; ascii <= c2; ++ascii){
    System.out.print(ascii);
  } 
  }catch(IOException e){System.err.println(e);}
 }
}
