Prototype

public static Object invokeMethod(Object object, String methodName, Object[] args)
        throws NoSuchMethodException, IllegalAccessException, InvocationTargetException

Document

Invoke a named method whose parameter type matches the object type.

This method delegates the method search to #getMatchingAccessibleMethod(Class,String,Class[]) .

This method supports calls to methods taking primitive parameters via passing in wrapping classes.
