Java Buffered Reader

Question

 import java.io.*;

 public class TerminateWhen
 {
   public static void main(String args[]) throws IOException
   {
     BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

     String str = "";
     System.out.println("Type \"x\" to exit..");
     do {
       str = br.readLine();
       System.out.println(str);
       }
     while(str!="x");
   }
 }

the problem is even if will type the "x", the loop will not exit..

Beware "standard" comparison operators when you're working with strings.

str != "x"

compares the two references, not the string's contents. Use the "equals" method to compare the string contents.

You must check for equals()
