Java // set some bits for(int i=0; i
Java bits2 AND bits1: {2, 4, 6, 8, 12, 14} bits2 OR bits1: {0, 2, 4, 6, 8, 10, 12, 14} bits2 XOR bits1: {} The Vector The Vector class is similar to a traditional Java array, except that it can grow as necessary to accommodate new elements. Like an array, elements of a Vector object can be accessed via an index into the vector. The nice thing about using the Vector class is that you don't have to worry about setting it to a specific size upon creation; it shrinks and grows automatically when necessary. For more details about this class, check The Vector. The Vector Class Vector implements a dynamic array. It is similar to ArrayList, but with two differences: Vector is synchronized. Vector contains many legacy methods that are not part of the collections framework. Vector proves to be very useful if you don't know the size of the array in advance or you just need one that can change sizes over the lifetime of a program. Following is the list of constructors provided by the vector class. Sr. No. Constructor and Description 1 Vector( ) This constructor creates a default vector, which has an initial size of 10 2 Vector(int size) 348
