Menu menu = menuService.findById(addMenuAmount.getMenuId())
.orElseThrow(com.tdk.web.exception.ResourceNotFoundException(“menu " +
addMenuAmount.getMenuId() + " not found "));
but I got a compilation Error:
com.tdk.web.exception cannot be resolved to a type

Optional.orElseThrowtakes aSupplierthat supplies/creates the exception. You appear to be passing the exception directly.

orElseThrowexpects aSupplieras its only parameter. You can use a lambda expression to return your exception which is to be thrown.Supplier's only method accepts no argument and in this case expects you to return anExceptionor a subclass.() -> new YourException()would suffice.

Try this and make sure that com.tdk.web.exception.ResourceNotFoundException is accesible
Menu menu = menuService.findById(addMenuAmount.getMenuId())
.orElseThrow(() -> new com.tdk.web.exception.ResourceNotFoundException("menu " +
addMenuAmount.getMenuId() + " not found "));
Note the lambda () -> and quotes "menu ".
