Can run, but there is no function

CodePudding user response:

WindowInput h=new WindowInput ();//input the topic number
N=h.T ran (); What is this used for? I n fixation of 10, is a function,, is it because your h.T ran ()==0,,, see you

I also started n is 10, yes, WindowInput h, is to define a class variable, quoting the JTextField variables in WindowInput inputNumber, I want to enter a number, and then appear as the number of questions and input digital, WindowInput is custom class, this also want to post? Or explain it?
