How to load My Jar to ClassPath at runtime through Java Coding?

Question

I am working with Swing in Net Beans. I have my own jar which contains classes and methods inside it. I will call those classes and methods using JAVA Reflection API but before

Answer 1

You can load classes at run time through the use of a ClassLoader, take a look at URLClassLoader for example

File yourJarFile = ...;
URLClassLoader classLoader = new URLClassLoader(new URL[]{yourJarFile.toURI().toURL()});

This will then allow you to load classes and instantiate them...

Class class = classLoader.loadClass("fully.qualified.packagename.to.your.AwesomeClass");

You can then instantiate them using something like...

Object obj = class.newInstance();

Or reflection if you want to use a specific constructor. Just remember, you won't be able to reference these classes directly within the current class loader context, as the current class loader knows nothing about them
