Question

while(responseChar == \"y\")

not sure what

Answer 1

Optionally you could use the big C Character class to convert your char to a String:

String converted = Character.toString(responseChar); 
while(converted.equalsIgnoreCase("y"))
{
  // ...
}

But this version is much more verbose than the literal comparison suggested by Jeffrey

Answer 2

To define a character literal, use a single quote: '. Double quotes define string literals.

while(responseChar == 'y')

Answer 3

Instead of "y" do this 'y'. "" Represents string.
