I forgot to mention that the Core class is a thread. I hope anyone gets my point though, someone must have had the same issue before. Horribly sorry for the messy description. But be careful: this method requires Demo to have a default construction method without parameters. And since that method is never called, the GUI class never gets a response, which leaves the GUI frozen. In future posts we will see how we can invoke more complex methods using Reflection. I have defined a simple method without any parameters. And since nothing is returned to that method, nothing is returned to Manager either. A method is invoked using Reflection as shown below : dynamic o2 meth.Invoke(a, null) Run it. The problem is that since it's self-invocing, it never stops running, right? And since it never stops running, nothing is ever returned to the first method in Core. That method in Core sets a local variable, and then calls another method in Core, that self-invokes itself. The method in manager then calls another method in a class called "Core". Java usually has a class first and then an object. Most frameworks also use the principle of reflection. Through reflection, private methods and private properties can be called. It mainly refers to the ability of a program to access, detect and modify its own state or behavior. 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 ()). The concept of reflection was first proposed by Smith in 1982. ![]() When that method is called, i call another method in an object called "Manager". Java reflection API: Invoking a method without parameters. ![]() In the GUI i have a button, and in the Swing class i have a method that is called whenever i click the button. I have a Swing class that displays the GUI. Execute a certain method of the object by calling the invoke method here you must pay special attention. Hopefully you understand it better than me though. So this is really complicated, it took me a while to realize what's actually happening.
