How to copy a value from one Frame to another Frame.

Question

Hi,
I am new to Swing and AWT prgramming .
I have created a menu called " Test window " and it contains toplevel menu item "File" and File Menu contains subitems "Product Evaluation", "ProcessEvaluation", "ResourceEvalation", "TotalEvaluation" and "Exit".
When i click File->Product Evaluation it displays a new Frame named frame1 , similarly if i click ProcessEvaluation , ResourceEvalation , TotalEvalation it displays frame 2 , frame 3 and frame 4 Respectively,
frame 1 , frame 2, frame 3 contains four textfields with names t1,t2,t3 and t4.(NOTE: I have given same names for textfields in all three frames so that in future i want to extend my GUI).
frame 4 contains 4 textfields with names t5,t6,t7,t8 and 4 buttons (b1,b2,b3,b4).
After i compile my program i will select ProductEvaluation and enter some values in textfield of frame 1 and minimise it. Similary i will open ProcessEvaluation and TotalEvaluation and enter values in textfields of frame2 and frame3 and minimise them.
My queston is now if i select TotalEvaluation and press Button1 in frame 4 it should display in textfield t5 the value extracted from t1 in frame1 added to the value extracted from t1 in frame 2 added to the value extracted from t1 in frame 3.
ie after pressing Button 1 textfield t5 should conatin value of t1 in frame1+ value of t1 in frame2 + value of t1 in frame3.
I am sending the code.
Can you please help me.

Answer 1

hi,
u have ot submit the values using
b1 for f1,
b1 for f2 and
b1 forf3
after u can access the values in to f4 other wise u con't
