We can add elements one by one or pass another collection toaddAll()elements in one step. It is helpful ininitializing an arraylist with valuesor existing objects from another collection of any type. HashMap<String,Integer>details=newHashMap<>();details.put("keanu",23);details.put("max",...
ThetoCollection()method is used to create a Collection using Collector. It returns a Collector that gathers the input data into a new Collection as shown in the below example. List<String>MyList=Stream.of("Value1","Value2","Value3").collect(Collectors.toCollection(ArrayList::new)); 4. C...
We can also play with the initializations as we like and initialize the lists with different numerical values or objects. 2. Using for Loop When thinking about the problem of initializing the ArrayList with a desired value or object, the first solution that comes to our mind is using ...

ArrayList is faster than vectors since they are unsynchronised. Conclusion We have covered some of the various methods to initialize the vector in C++. You can choose to use any of the methods according to your requirements. Vectors are one of the most important concepts in STL. So gaining go...
