Representration of a Empty Class Array
I am actually looking at getting the method, whose name is stored in the string "methodName", from the Class "CC1" using Java Refl开发者_Go百科ection.
Method actualMethod= CC1.getMethod(methodName, parameterTypes);
This is the syntax. The problem is the method takes no parameter. How do I represent that in the parameterTypes ?
where parameterTypes is the array of Class
Similarly, the below code will invoke that method.
Object retobj = actaulMethod.invoke(actualObject, arglist);
The arglist is array of Objects which again has to be nothing.
If anything is unclear , please ask. Thanks .
Don't pass the second argument:
CC1.getMethod(methodName);
(This makes use of varargs)
This is equivalent to passing an empty array:
CC1.getMethod(methodName, new Class[] {});
The signature is:
Method getMethod(String name, Class... parameterTypes)
So just leave the second parameter out and it should work. i.e.
Method actualMethod= CC1.getMethod(methodName);
