How to invoke method with variable arguments in java using reflection? or How to invoke a method in java using reflection but these use methods names: ("test", int.class) which is not what I'm trying to do. Note that we compiled following class with -parameters option of the compiler to include the method parameter names in source class ( more info) package import java.io. class files do not store formal parameter names by default.
And, using the object we can call various methods to get information about. (The classes Method and Constructor extend the class Executable and therefore inherit the method Executable.getParameters. In order to reflect a Java class, we first need to create an object of Class. I've seen a number of similar questions here, e.g. You can obtain the names of the formal parameters of any method or constructor with the method .getParameters.
The method I want to invoke (I know it's public but I need to use reflection): public byte myMethod () I get the Method object like this and m contains myMethod () (I checked with the debugger) Method m Class.forName (M圜 ()). We invoke the getString1() method on our Testing object by calling invoke() on the Method object. Java reflection API: Invoking a method without parameters. Since getString1() has no parameters, this array is empty. I'm trying to invoke a method with an unknown number of parameter (when being invoked) using reflection. The first parameter is the getMethod() call is the method name, and the second call is an array of Class objects representing the parameters of the getString1() method.
