I am using reflection to get return type of method which is String.
When I invoke function I need to cast return value to String.
How can I do that without explicitly using String and instead to use returnType obtained through reflection?

Main.java

Class   returnType = method2.getReturnType();         System.out.println(returnType.getName());

String   hello1    = (String)          method2.invoke(personObject, "Susan", 40);
String   hello2    = (java.lang.Strin) method2.invoke(personObject, "Susan", 40);
String   hello2    = String.class.cast(method2.invoke(personObject, "Susan", 40));

String   hello2    = Class.forName("String").cast(method2.invoke(personObject, "Susan", 40));

Person.java

public class Person {

  public String sayHelloTo(String name, int age) {
    return "Hello " + name + ", you are " + age + " years old";
  }

}
