Software testing-Leap year testing

First, the procedure requirements

How to determine a leap year:

1, the ordinary year can be divisible by 4 and not divisible by 100 for leap years. (such as 2004 years is a leap year, 1900 is not a leap year) 2, century can be divisible by 400 is leap years. (For example, 2000 is a leap year, 1900 is not a leap years) normally in a text box, enter an age, click the OK button, the program will determine whether the year to ask leap years, but if the input is a string or a negative number, the program will produce an exception, and this blog is to solve the problem. Second, the test analysis

Number	Input	Output
1	2000	It's a leap year.
2	1900	1900 is isn't a leap year.
3	Sdafsd	Input Invalid.
4	-100	Please input a positive number.

Third, the code implementation

Add (text); Anchorpane.settopanchor (text,30.0); Anchorpane.setleftanchor (text,90.0); FinalTextField input =NewTextField ();        Root.getchildren (). Add (input); Anchorpane.settopanchor (Input,50.0); Anchorpane.setleftanchor (Input,90.0); Button Submit=NewButton (); Submit.settext ("Submit");        Root.getchildren (). Add (Submit); Anchorpane.settopanchor (Submit,50.0); Anchorpane.setleftanchor (Submit,240.0); Submit.setonaction (NewEventhandler<actionevent>() {             Public voidhandle (ActionEvent arg0) {Final intYear =Integer.parseint (Input.gettext (). toString ()); Stage Newstage=NewStage (); Anchorpane Newroot=NewAnchorpane (); Text result=NewText (); Try{                    if((year% 4 = = 0 && Year% 100! = 0) | | (Year% 400 = = 0) {Result.settext ( year+ "is a leap year."); }                    Else{Result.settext ( year+ "isn't a leap year."); }                } Catch(Exception e) {Result.settext ("Input Invalid"); }                                if(Year < 0) {Result.settext ("Please input a positive number.");                } newroot.getchildren (). Add (Result); Anchorpane.settopanchor (Result,20.0); Anchorpane.setleftanchor (Result,30.0); Newstage.setscene (NewScene (Newroot, 250, 50));            Newstage.show ();                }        }); Stage.setscene (NewScene (Root, 400, 100));    Stage.show (); }}
