Read the Value from the console in selenium using java-junit4

Hi,

I tried to read the value from the console. My code asking value but it won't read the given value.

My code is

BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Do u want to add another Knowledge Hub? y/n");
String s = br.readLine();
while(s=="y"){
WebElement khub = this.currentBrowser.findElement(By.id("edit-field-chall-kw-reference-0-nid-nid"));
khub.sendKeys("mechanics");
System.out.println("Do u want to add another Knowledge Hub? y/n");
}

Is it possible in selenium..
Please help me...
Thanks,
