Differentiate between array list and vector in java.

Following are some of the differences between array list and vectors in JAVA: –

• An array list is not synchronized, whereas a vector is synchronized.
• An array list works fast, whereas a vector does not.
• There is an increase of 50% in the array size whenever any element is inserted inside the array list, whereas vector defaults to doubling the size of its array.
• The increment size is not defined in an array list, whereas in vector it is defined.
• Only iterators can be used in an array list for traversing an array, whereas vectors can use both enumeration and iterators for traversing an array.
