InvokeStaticMethod(Class, String, Object, Class). Invokes a named static method whose parameter type matches the object type. Parameters: object - invoke method on this object forceAccess - force access to invoke method even if it's not accessible methodName - get method with this name args - use these arguments - treat null as empty array parameterTypes - match these parameters - treat null as empty array Returns: The value returned by the invoked method Throws: NoSuchMethodException - if there is no such accessible method InvocationTargetException - wraps an exception thrown by the method invoked IllegalAccessException - if the requested method is not accessible via reflection Since: 3.5 param name the name of the static method. Parameters: object - invoke method on this object forceAccess - force access to invoke method even if it's not accessible methodName - get method with this name args - use these arguments - treat null as empty array Returns: The value returned by the invoked method Throws: NoSuchMethodException - if there is no such accessible method InvocationTargetException - wraps an exception thrown by the method invoked IllegalAccessException - if the requested method is not accessible via reflection Since: 3.5 Through reflection we can access the private variables and methods of a class with the help of its class object and invoke the method by using the object as. Reflection.staticMethod(.) Starting point of the fluent interface for invoking static methods via reflection. InvokeMethod(Object object, boolean forceAccess, String methodName, Object args, Class parameterTypes). invokeMethod public static Object invokeMethod( Object object,.Parameters: object - invoke method on this object methodName - get method with this name args - use these arguments - treat null as empty array Returns: The value returned by the invoked method Throws: NoSuchMethodException - if there is no such accessible method InvocationTargetException - wraps an exception thrown by the method invoked IllegalAccessException - if the requested method is not accessible via reflection InvokeMethod(Object object, String methodName, Object args, Class parameterTypes). This method supports calls to methods taking primitive parameters class) Map hm new HashMap<> () method.This method delegates the method search to getMatchingAccessibleMethod(Class, String, Class). We can use invoke () method of Method object to invoke a method, in below example code let's invoke put method on HashMap using reflection. Invokes a named method whose parameter type matches the object type.
