![]() ![]() This data is bundled inside the Package class, which is returned by a call to getPackage method on the class object. ![]() Let’s take a look at the code snippet that follows:Ĭlass clazz = įor (int i = 0 i < methods. By using Java reflection, we are also able to get information about the package of any class or object. For all elements in the array get the return type for the method each object represents, using getReturnType() API method of Method.This method returns an array of length 0 if the class or interface declares no methods, or if this Class object represents a primitive type, an array class, or void. The returned array doesn’t include classes declared in inherited classes and interfaces. The elements in the array returned are not sorted and are not in any particular order. getDeclaredClasses () method returns an array of Class objects reflecting all the classes and interfaces declared as members of the class represented by this Class object. Once you have the Method object, you can use invoke () to call the method it represents. This represents the capability to call a method that belongs to the class that the method object was created from. If the return type is a type variable or a parameterized type, it is created. You may also call getMethod () to retrieve a method object from the class object. If the return type is a parameterized type, the Type object returned must accurately reflect the actual type parameters used in the source code. This includes public, protected, default (package) access, and private methods, but excludes inherited methods. Returns a Type object that represents the formal return type of the method represented by this Method object. Get the array of Method objects reflecting all the methods declared by the class, using getDeclaredMethods() API method of Class. You can still explicitly choose between a get lookup on the given class level only ( getAnnotation(Method, Class) ) and a find lookup in the entire.Using the Reflection API, it is possible to change or get the value of a field at. This is an example of how to get the return type of a classe’s methods. To get the return type of a classe’s methods one should perform the following steps: Method // This is a object representing the String class (not an. ![]()
