Whye does my Thread.wait() method apply to the whole program
I have GUI application that I want control with buttons. when I press one button(start) I want to execute one methode that calculates some numbers and prints out the result. Since there are severeal result I want the method to wait after the first answer, and I when i press my other button(continue) I want the method to continue and show me the next answer.
My problem is when I press the start button and get to the wait() method the whole application just freeze. The whole app seems to wait. I have tested with wait(some miliseconds) and the case is same. The whole app waits for some seconds and then continues. The clue is that i dont want the whole app to wait, only the method that prints out.
Here is the thread class. The only one in the code.
I also have a class that extends JFrame to build up the GUI. In that class I have a inne actionlistener class where I listen when the buttons are clicked.
When the button start is clicked it calls a method that gets a user input and sends it to the testNumber method. When the method is called it should stopp after the wait(); When I then press my other button it should continue. The continue button has only a notify() method.
