The trimToSize() method of java.util.Vector class trims the capacity of the vector to be the vector’s current size. If the capacity of the vector is larger than its current size, then the capacity is changed to equal the size by replacing its internal data array, kept in the field elementData with a smaller one.
Java Vector toString() Example
The toString() method of java.util.Vector class returns a string representation of the Vector, containing the String representation of each element.
Java Vector toArray() Example
The toArray() method of java.util.Vector class returns an array containing all of the elements in the vector in proper sequence (from first to last element).
Java Vector subList(int fromIndex, int toIndex) Method Example
The subList(int fromIndex,int toIndex) method of java.util.Vector class will return a view of the portion of this List between fromIndex(inclusive) and toIndex (exclusive). If fromIndex and toIndex are equal, the returned List is empty.
Java Vector size() Example
The size() method of java.util.Vector class will return us the actual size of the vector(Count of number of elements present in the vector).
Java Vector setSize(int newSize) Method Example
The setSize(int newSize) method of java.util.Vector class will sets the size of the vector. If the new size is greater than the current size, new null items are added to the end of the vector. If the new size is less than the current size, all components at index newSize and greater will be discarded.
Java Vector setElementAt(E obj,int index) Example
We have already seen set(int index, E element) method of java.util.Vector class will replace the element at the specified position in the Vector with the specified element, sameway setElementAt(E obj,int index) method will set the element at the specified index of this vector to be the specified object.The previous element at that position will be discarded.
Java Vector set(int index, E element) Method Example
We have already seen add(int index, E element) method of java.util.Vector class which will insert the specified element at the specified position in the Vector and shifts the element currently at that position to the right and the new element will added at that index. whereas set(int index, E element) method will replace the element at the specified position in the Vector with the specified element.
Java Vector retainAll(Collection c) Method Example
The removeAll(Collection<?> c) method of java.util.Vector class will remove all the content of the Vector, whereas retainAll(Collection<?> c) method will retain only the elements in the Vector that are contained in the specified Collection.

Java Vector removeRange(int fromIndex,int toIndex) Method Example
The remove(int index) and removeElementAt(int index) method of java.util.Vector class removes the element at the specified index. Each component in this vector with an index greater or equal to the specified index is shifted downward to have an index one smaller than the value it had previously whereas removeRange(int fromIndex,int toIndex) method removes from the vector all of the elements whose index is between fromIndex inclusive and toIndex exclusive
