Passing a parameter to the constructor and calling a method dynamically

   
public class Main {
  public static void main(String args[]) throws Exception{
      String name = "java.lang.String";
      String methodName = "toLowerCase";

      Class cl = Class.forName(name);
      java.lang.reflect.Constructor constructor = cl.getConstructor(new Class[] { String.class });
      Object invoker = constructor.newInstance(new Object[] { "AAA" });
      Class arguments[] = new Class[] {};
      java.lang.reflect.Method objMethod = cl.getMethod(methodName, arguments);
      Object result = objMethod.invoke(invoker, (Object[]) arguments);
      System.out.println(result);
  }
}
