newInstance() 已弃用,使用clazz.getDeclaredConstructor().newInstance()

Browse Source 
This method propagates any exception thrown by the nullary constructor, including a checked exception. Use of this method effectively bypasses the compile-time exception checking that would otherwise be performed by the compiler. The Constructor.newInstance method avoids this problem by wrapping any exception thrown by the constructor in a (checked) InvocationTargetException.
The call
 clazz.newInstance()
can be replaced by
 clazz.getDeclaredConstructor().newInstance()
The latter sequence of calls is inferred to be able to throw the additional exception types InvocationTargetException and NoSuchMethodException. Both of these exception types are subclasses of ReflectiveOperationException.
