I'm pretty new to Java, and I'm facing a reflection issue.
Let's say i have to dynamically call the method fooMethod on an instance of the class Foobar
I got so far an instance of Foobar with:
Object instance = Class.forName("Foobar").newInstance();
Let's say I know there's a method fooMethod on this object (I can even check this with Class.forName("Foobar").getDeclaredMethods() ) , how to call it, please?
Class.forName("Foobar").newInstance();
is now deprecated (https://docs.oracle.com/javase/9/docs/api/java/lang/Class.html#forName-java.lang.Module-java.lang.String-)
Class.forName("Foobar").getDeclaredConstructor().newInstance()
or if you need a specific constructor:
Constructor constructor = Class.forName("java.lang.String").getConstructor(String.class);
String object = (String) constructor.newInstance("Hello");
