Why Is Loop Outputting Line Twice

I have a loop and I was wondering why it is outputting my line twice. Here is the code:

while (x != -1) // closes the program if the user enters -1 for x
{
System.out.println("Which jar would you like to access? Please select a number between 1 and 3. Press -1 to exit.");
x = scan.nextInt();
ourpantry.Selection(x); // tells our pantry class what number the user selected
while ((response != "continue")) // loop continues until user gives a valid response

[Code] ....

This results in the Output:

Would you like to spread jam? Y or N.
Would you like to spread jam? Y or N.
