This is my entire code...
i want to take the values from the function tri() and use them to set the values of textfields in tri1()...
For ex the load_class_cnt should be retrieved in the tri1() so that i can set the text field to its value...

Please help.....

That is because the variables you are using to store the values in tri() cannot be used outside that method; they are local variables and can be used only inside that method.
One suggestion is to make your methods non static, and declare the variables that you will store the values outside the methods so they will be global. Then since you are using two different classes you should pass those variables as arguments at the method where you are setting the text.

Now I hope the code appears much better and small as compared to the earlier one...

Here you see that I have retrieved the values in the class Trial's tri() function.. I want to reflect these values in the JTextfield in the Trail1's tri1() function.. When I try to do this using the setText method, it does not support.. Basically I need to access the variables in Trial class through Trail1() and I am unable to do that..

Can you help please???

I have tried my hand at what you suggested and also been able to resolve the problem to some extent...
thanks for the help..

but when i retrieve the values in the class and try to print them in the JTextField, it does not give any ouput..
the text fields remain blank..
Can you see what the problem exactly is..??

Please help me with the code...
