How can I determine whether a Java class is abstract by reflection
It'll have abstract as one of its modifiers when you call getModifiers() on the class object.
This link should help.
Modifier.isAbstract( someClass.getModifiers() );Also:

public static boolean isInstantiable(Class<?> clz) { if(clz.isPrimitive() || Modifier.isAbstract( clz.getModifiers()) ||clz.isInterface() || clz.isArray() || String.class.getName().equals(clz.getName()) || Integer.class.getName().equals(clz.getName())){ return false; } return true;}
