Java application and WINDEV
A Java application is an application entirely compiled in Java...
Manipulating a database from a Java application
You can start developing your application as soon as the WINDEV project is defined as being a Java project...
Using Java code
You have the ability to enter Java code:
  • in Java applications generated with WINDEV.
  • in Android applications generated with WINDEV Mobile.
This allows you to create global procedures in Java.
Available features and specific features of Java
WINDEV allows you to generate a Java application without even knowing the Java language...
Managing databases in WINDEV Java applications
This document presents the different access modes to databases from a WINDEV Java application...
Testing a Java project and compiling it
When your Java application is developed, you can run the test of the Java project and compile it before creating the archive...
Creating a Java project
WINDEV allows you to generate a Java application without even knowing the Java language...
Properties available in Java
WINDEV allows you to generate a Java application without even knowing the Java language...
