readline Error 2
1 Answer(s)      7 years ago
Posted in : Java Beginners
Hi sir,
can you look again please.
The error is hard to notice, but if you execute the code,
1. enter a string the first input request (eg hello world),
2. ENTER

3a. ENTER n for the next input request
The code will not terminated after the 'n'. This is because the first char is missing and from the readLine(). You would have to to enter 'nn'
for the code to exit. I think the problem is caused by the read() statement, just don't know why.

3b. ENTER another string for the next input request (eg bye world)
The code will output text "ye world", again the first char (b) is missing.

Could you please check again. I have to use the System.in.read() for this home work.

Thanks for the quick response
thanks sella

Hi Friend,

Use br.readLine instead of System.in.read, your code will work.

Your modified code:

import java.io.*;
class TestAdvt{
public static void main (String[] args){
boolean done=false;
while (!done){
BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
String str = null;
try{
System.out.println ("Please enter the advertisement message to be displayed (enter 'n' to exit)");
str = br.readLine();
if (!str.equalsIgnoreCase("n")){
System.out.println ("str1 = " + str);
Thread advt = new Thread(new Advertisement(str));
advt.start();
br.readLine();
advt.interrupt();
}
else{
System.out.println ("str2 = " + str);
done = true;
}
}
catch (IOException e){
System.out.println("IOException caught: " + e.getMessage());
}
}
}
}
class Advertisement extends Thread{
private String message;
Advertisement (String message) { this.message=message;}
public void run(){
while (!message.equals("")){
try{
System.out.print(message+".. ");
Thread.sleep(1000);
}
catch (InterruptedException e){
this.message="";
break;
}
}
}
}

Thanks
