What are the methods of Vector in Java?
Java Vector Methods
| SN | Method | Description |
|---|---|---|
| 4) | capacity() | It is used to get the current capacity of this vector. |
| 5) | clear() | It is used to delete all of the elements from this vector. |
| 6) | clone() | It returns a clone of this vector. |
| 7) | contains() | It returns true if the vector contains the specified element. |
How do you create a Vector in Java?
Three ways to create vector class object:
- Method 1: Vector vec = new Vector(); It creates an empty Vector with the default initial capacity of 10.
- Method 2: Syntax: Vector object= new Vector(int initialCapacity)
- Method 3: Syntax: Vector object= new vector(int initialcapacity, capacityIncrement)
How do you Vector a Vector in Java?
You can create a 2D Vector using the following:
- Vector> vector2D = new Vector>(10); This will create a Vector of size 10 which will contain Vectors with Integer(Vector) values.
- vector2D. add(2, new Vector(10));
- Vector rowVector = vector2D. get(2); rowVector.
What is Vector List any two methods?
Methods of Vector: 1) void addElement(Object element): The object specified by element is added to the vector. 2) int capacity() : It returns the capacity of the vector. 3) Object clone() : It returns a duplicate copy of the invoking vector.
What are the methods of vector class in Java?
The following are the methods that are supported by Vector class in Java. Adds given element to the end of the vector. Add element to the vector at the specified index. Adds all the elements from given collection to the end of vector. Adds all the elements in the specified collection at specified index.
How do you create a vector in Java?
Vector (int size, int incr): Creates a vector whose initial capacity is specified by size and increment is specified by incr. It specifies the number of elements to allocate each time that a vector is resized upward. Vector (Collection c): Creates a vector that contains the elements of collection c.
How to enumerate elements in a vector in Java?
The elements () method of Java Vector class used to get an enumeration of the elements of the vector which is in use. The returned enumeration object will generate all items in this vector at the same location. This method does not accept any parameter. The elements () method returns an enumeration of the elements of this vector.
Are there legacy methods in vector in Java?
Vector contains many legacy methods that are not part of collection framework which we will discuss below with examples in java. This method adds element at the end of the vector, as shown in the following program:
