Block input while JDialog is open

Question

I'm trying to make an RPG game in java and I wanted to show a PNG image. The problem is all game is on the console (it is a text-base game) except the image that I open with JDialog, when I open the image, the consoles freezes (what I wanted to do), but if I write on the console while frozen, the scanner will catch what I typed and when I close the Image will run what I typed. I tried to reset the scanner but it didn't work.

Here's an exemple:
What I wanted to do:
(Show image)
User type: hello
(User closes image)
Type something:
User type: bye
You typed bye, right?

What happens:
(Show image)
User type: hello
(User closes image)
Type something: hello
You typed hello, right?

Here's what I'm doing: https://code.sololearn.com/c1OU22Xs7mrZ

Answer 1

try this

stdin.skip(".*");
System.out.print("Type something: ");

Answer 2

The stdin.skip(".*") didn't work alone, but it'll work if you do this:

stdin.skip(".*");
stdin = new Scanner("System.in");
System.out.print("Type something: ");

But I don't know how safe it is to do this...

Answer 3

it should be ok
