It is required to make a class loader for java

Question

It is required to make a class loader from a file for java.

I heard that this is done by overriding the ClassLoader operators, how can this be done?

On the Internet is not one normal instructions.

Implementing your Classloader is somewhere above the advanced level of Java knowledge, and what you need is probably the JavaCompiler API, dig in this direction.
Corrected) no I do not need to make my Classloader, I need to make a Classloader that works like a regular Classloader but loads classes from a file.
you need to implement your ClassLoader) And where does your default ship from?

Found a very good example . The only pity is that the link to the original is broken.

Option - use URL:

// Создайте объект File в корне директории, которая содержит class-файл. File file = new File("c:\\myclasses\\"); try { // Преобразуйте File в URL URL url = file.toURI().toURL(); // file:/c:/myclasses/ URL[] urls = new URL[]{url}; // Создайте новый class loader с директорией ClassLoader cl = new URLClassLoader(urls); // Загрузите класс; MyClass.class должен располагаться в // директории file:/c:/myclasses/com/mycompany Class cls = cl.loadClass("com.mycompany.MyClass"); } catch (MalformedURLException e) { } catch (ClassNotFoundException e) { }

Yes, everything works fine) is a good example. - Denis Kotlyarov
