Hi I am Making a horse racing application .... and the concept is when you enter a number in the textfield and select a horse(one of the 8 jButtons) the application will randomly select one of the JButtons and if the Jbutton is the same as the one selected by the user it will multply the value entered in the textfield by the value assigned to the Jbutton .

im stuck on how to randomly pick a Jbutton
