Java Question HELP CREATE A LIBRARY

[PABLO2013]

CHEERS
I WANT TO KNOW YOU CAN BE WRONG IN THIS LIBRARY IF YOU CAN HELP ME , THANK YOU

 

[Johan Schoeman]

Your class name is not the same as your file name. Your class is called PairwiseComparisonMatrix while your file name is PairwiseComparisonMatrix1. Rename your file to PairwiseComparisonMatrix

WHY ARE YOU SHOUTING????

 

[DonManfred]

You lib will not work on Android. Maybe on B4J it can run.

import javax.swing.*;         
//This is the final package name.
//import com.sun.java.swing.*; //Used by JDK 1.2 Beta 4 and all
//Swing releases before Swing 1.1 Beta 3.
import javax.swing.border.*;

import java.awt.*;
import java.awt.event.*;

javaxy.swing and java.awt are NOT available on Android

Note: src\b4a\example\starter.java uses or overrides a deprecated API.

There is an example here including the Java code

Confirmation number

Perhaps not the best (public) place to put such information : conversation could be better used (search engines visit us frequently)

 

[DonManfred]

conversation could be better used

Well spoken and fully agree

PD: But if i want to create a new conversation with you i get told that i is not possible to me to do that

@DonManfred : I am sorry, I had thought to have fixed my settings. (Checking again)

 

[DonManfred]

Checking again

And if you are already checking things; Check this out if you are using a Samsung device ;-)

Pablo, the attached project compiles:
1. Note the libs folder that I have added. Inside this folder is Jama-1.0.2.jar
2. You also need to have this jar (Jama-1.0.2.jar) inside your B4J additional library folder once you run your B4J project
3. I have not used eclipse but @Erel's Simple Library Compiler for B4J libraries. It is available on the forum to download. Just make sure you use the one that goes with B4J and not the one that goes with B4A (I don't use Eclipse at all - I only use Notepad++ and Simple Library Compiler for all my libraries).

Thanks for your time,
I do not explain much but the idea is that this library work in B4A and not B4J , similar to how you do it in your project jama (https://www.b4x.com/android/forum/threads/jama-a-java-matrix-package-b4a-wrapper-in-post-3.59192/) , help is to see how it should indicate the constructors , the initialization function and others to work in BA4, so far have been experimenting with javaobjet and could be a option, because my library is not very big , but I'm interested to see how it can be implemented in a additional library to see and grab practice .... the part of the library has in "swing"..... because the original code was so , but as I repeat myself interested in BA4.
You 're right, the library compiles (in this part only my knowledge) and do not know how to connect and work this with BA4.

thanks

See my answer here: https://www.b4x.com/android/forum/threads/help-create-a-library.64219/#post-406391
java.swing and java.awt are NOT(!!!) Available on Android. This Library WILL NOT WORK ON ANDROID!

Don Mafred, you are right, what happens is that I copy bad code and copy with calls to "swing" but the idea is that i can use in B4A, the code works well on the console Eclipe , but this just use it to check the code..... by dispersing in how to use it in B4A , but my problem is not how to do it .... so I appeal to your kind work , tks
