On the further deepening of the last equivalence class test

This week, I'm going to try to make further changes to the little program that I wrote last time for equivalence class testing, making it more complex and specific. The new requirement is to change the last input box to three input boxes.

and requirements for each number of boxes are satisfied:

Allow 1 to 6 English characters or numbers, press OK to end

First of all, the changes in the program is not too much, because I am using Java, first in the layout to make changes, add GridLayout, add two input text box. Second, in logical judgment,

There is not much change, nothing more than a synthesis of three boxes of input judgment results to make a final judgment, determine whether the input is legitimate

This is the part that makes a change to the layout of the interface

PrivateJButton sure =NewJButton ("OK"); PrivateJTextField input =NewJTextField (Ten); PrivateJTextField INPUT1 =NewJTextField (Ten); PrivateJTextField Input2 =NewJTextField (Ten); Hellow () {borderlayout borderlayout=NewBorderLayout (5,5);  This. setlayout (BorderLayout); GridLayout Grid=NewGridLayout (3,1); FlowLayout F1=NewFlowLayout (Flowlayout.center,Ten,Ten); FlowLayout F2=NewFlowLayout (Flowlayout.center,Ten,Ten); FlowLayout f3=NewFlowLayout (Flowlayout.center,Ten,Ten); JPanel P1=NewJPanel (F1); P1.add (NewJLabel ("NAME1:"));        P1.add (input); JPanel P2=NewJPanel (F2); P2.add (NewJLabel ("NAME2:"));        P2.add (INPUT1); JPanel P3=NewJPanel (F3); P3.add (NewJLabel ("NAME3:"));        P3.add (INPUT2); JPanel P4=NewJPanel (GRID);        P4.add (p1);        P4.add (p2);        P4.add (p3);        Add (P4, Borderlayout.center); JPanel Login_button=NewJPanel (NewFlowLayout (Flowlayout.right, -,                Ten));        Login_button.add (sure); Add (Login_button, Borderlayout.south);

Next, the code is as follows in logical judgment

intnum =input.gettext (). Length (); intNUM1 =input1.gettext (). Length (); intnum2 =input2.gettext (). Length (); if(num = =0|| num >6|| num1==0|| NUM1 >6|| num2==0|| Num2>6) {wronginput (); return; } String Temp=Input.gettext (); String Temp1=Input1.gettext (); String Temp2=Input2.gettext (); if(Temp.matches ("[0-9a-za-z]*") &&temp1.matches ("[0-9a-za-z]*") &&temp2.matches ("[0-9a-za-z]*") ) System. out. println ("OK"); Elsewronginput ();

First determine whether each input box satisfies the input word Fushun length between 1-6, otherwise directly prompt illegal, and then to each input box input content to judge, if there is a box

If the input is not valid, an illegal prompt is given, and if correct, the output is OK.

	valid class	invalid class
first line input box character length	length is 1-6	empty string
		length greater than 6
First line Input box character contents	belongs to numbers, uppercase and lowercase	control characters
		punctuation
second Line input box character length	length 1-6	empty string
		length greater than 6
the second line of input box character contents	is numeric, uppercase and lowercase	control characters
		punctuation
Third line input box character length	length 1-6	empty string
		length greater than 6
The third line of input box character contents	is numeric, uppercase and lowercase	control characters
		punctuation
