Invoking a static method using reflection
// String.class here is the parameter type, that might not be the case with youMethod method = clazz.getMethod("methodName", String.class);Object o = method.invoke(null, "whatever");In case the method is private use getDeclaredMethod() instead of getMethod(). And call setAccessible(true) on the method object.
Fromthe Javadoc of Method.invoke():
If the underlying method is static, then the specified obj argument is ignored. It may be null.
What happens when you
Class klass = ...;Method m = klass.getDeclaredMethod(methodName, paramtypes);m.invoke(null, args)
String methodName= "...";String[] args = {};Method[] methods = clazz.getMethods();for (Method m : methods) { if (methodName.equals(m.getName())) { // for static methods we can use null as instance of class m.invoke(null, new Object[] {args}); break; }}
