How to make sure the overrided method is also synchronized in Java?

It cannot be guaranteed. However an workaround would be to create a synchronized method and invoke an abstract method from it. We also need to ensure the abstract method is directly invoked.

public synchronized final void method() {
    absMethod();
}
protected abstract void absMethod();

I have one List of Map like - List> list = new ArrayList>(); I want to return the Key if any value passed by user is equal to the value present in Map using Java 8 . One way to doing is - Map data = new HashMap<>(); list.stream().forEach(map -> { data.putAll(map.entrySet().stream() .collect(Collectors.toMap(entry -> entry.getKey(), entry -> (String) entry.getValue()))); }); String result = data.entrySet().stream() .filter(map -> "def".equals(map.getValue())) .map(map -> map.getKey()) .collect(Collectors.joining()); But I want to do to it without using collect().
