what is the purpose of the sending if the variable isnt saved?

So whjat you are saying is i should remove index2 instance from index

go to mainpage then change one = new Index2() to.......what?

"one = new Index2();" MainPage.java
"Index2 index2 = new Index2();" Index.java

while you wait while i convert all the buttons...

It would require an external library from intellij. I have once again included all source files included the hidden gui portion to this link. This...

so i started from scratch and passed variables. I got it down pat.

im just not getting this at all. Im staring at your response with confusion. Can you clearly outline what is suppose to be in Index and Index2 and post the corresponding code? Im very confused what...

the setindex2 is placed in index. was this suppose to be placed in index2?

and the index2.setter() is placed in index?

Im really confused, because it feels like those 2 classes is just slinging...

i get what you are saying but im having a hard time visualizing it.

the index has a reference to Index.

Im trying to send the value of lblamnt or tvar that is in index.java and pass that variable to index2 so i can perform calculations and such.

the lblamnt is a JLabel and tvar is a String.

3326

The data type isnt in the error.

its looking for a variable to be sent in the Index2().

So is this the part where i send the value of lblamnt/tvar in index?

How would i call that value in here?

MainPage.java



one = new Index2();


"Index2(Index) in Index2 cannot be applied"

thank you norm, that was my own careless mistake. I fixed those and put it in the class. It resolved the errors for index and index2.

MainPage still persists.

index.java


public void setIndex2(Index2 index2){
Index2 Index2;
this.index2 = index2;
}


index2.java

those are already in index and index2, i have to put this again in mainpage?

can you provide an example on how this would be?

i learn best when an example of code is displaced with a brief explanation.

I have updated the code according to brynpttrsn.

MainPage.java



import javax.swing.*;
import java.awt.*;

public class MainPage extends JDialog {

"If the latter, if a reference to the instance of Index is passed to the constructor of Index2 when Index2 is created, the code in Index2 could use tht reference to call a getter method in Index."

by viewing the code i posted previously how can i resolve this problem.

Recap. I need the value of lblamnt or tval to be carried to index2 so i can pull. I tried doing a getter function but it...

Please stand by, im figuring out how this works. apparently there is an option that auto generate the code.
