defineClass() is a protected method of the ClassLoader class that allows you to convert a byte array into an instance of the class 'Class'.

I added the ability to use this method in any ClassLoader and extended its functionality.

/*
 * Example of creating a new instance
 * of a compiled Test.class
 * with defineClass()
 */
try {
    Class<?> testClass = Define.defineClass(
            getClass().getClassLoader(),
        Paths.get("./classes/Test.class"));
    testClass.newInstance();
} catch (Exception e) {
    throw new RuntimeException(e);
}
