Difference between Vector and Arraylist is the most common Core Java Interview question you will come across in Collection . This question is mostly used as a start up question by the Interviewers before testing deep roots of the Collection . Vector , ArrayList classes are implemented using dynamic...
The vector was not the part of collection framework, it has been included in collections later. It can be considered as Legacy code. There is nothing about Vector which List collection cannot do. Therefore Vector should be avoided. If there is a need of thread-safe operation make ArrayList s...
As per the Vectorjavadoc, the Enumeration returned by Vector is not fail-fast. On the other side the iterator and listIterator returned by ArrayList arefail-fast. Legacy?: The vector was not the part of collection framework, it has been included in collections later. It can be considered as...
the programmer does not need to know the size of the arraylist when he/she is defining it. Vector can also be seen as an array that can grow in size. Vectors can be easily allocated and can be used to when the required size of the storage is not known until runtime. ...
Avectoris a quantity that specifies both a magnitude and a direction. Such a quantity may be represented geometrically by an arrow of length proportional to its magnitude, pointing in the assigned direction. Examples of vectors are: displacement, velocity, acceleration, force and electric field. V...
