In this example get the Class instance of Math class. You can list the public and private methods of an object using the following steps: Get the Class instance of the class which you want to list the methods. If you could point out my mistake, I would really appreciate it. In this example we shall explain with a simple example to get the methods of a class using the reflection and get the return type. The class I am reading in is called myclass2 which is here: package a8 Īs you can see, the method does infact exist in the class. And, using the object we can call various methods to get information about. For example, to find a backing field or a Java method that serves as a getter for a Kotlin property, you can write something like this: import . In order to reflect a Java class, we first need to create an object of Class. This is the function I use to read in a class from my main function, and then I want to getMethod() with the parameters "test" and null, where "test" is the name of the method and null means the method has no parameters. On the JVM platform, the standard library contains extensions for reflection classes that provide a mapping to and from Java reflection objects (see package ). Why does it append the class part? (the a8 is correct, so don't worry about that) /EDIT1 Method method1 = cls.getMethod("test", null) ĮDIT1:When I print out "Cls: "+cls, the output is "Cls: class a8.myclass2". static void methodInfo2(String className) throws ClassNotFoundException, However, when I do this I get a NoSuchMethodException, and I was hoping you could tell me why my implementation is incorrect. I need to get a method that matches specifications as described by the getMethod() function. I'm working with the basics of Java reflection and observing information on methods of classes. The methods of a class can be listed using the () method.
