e116. Getting a Constructor of a Class Object
There are two ways of obtaining a Constructor object from a
Class object.
// By obtaining a list of all Constructors object.
Constructor[] cons = cls.getDeclaredConstructors();
for (int i=0; i<cons.length; i++) {
Class[] paramTypes = cons[i].getParameterTypes();
process(cons[i]);
}
// By obtaining a particular Constructor object.
// This example retrieves java.awt.Point(int, int).
try {
Constructor con = java.awt.Point.class.getConstructor(new Class[]{int.class, int.class});
process(con);
} catch (NoSuchMethodException e) {
}
