You are probably talking about assigning values directly when writing fields. This is similar to assigning a value in the constructor. However, writing it directly on the field is generally regarded as the default value. If you need to pass in different values according to the situation, you need a constructor.
If you have multiple constructors, and some constructors do not initialize some member variables, then the remaining member variables do not have default values set, something may go wrong
