Java Vector get() Method
Description
The Java Vector get(int index) method is used to return the element at the specified index position in this Vector.
Declaration
Following is the declaration for java.util.Vector.get() method
public E get(int index)
Parameters
index − This is the index position of the element to be returned
Return Value
The method call returns the object at the specified index.
Exception
ArrayIndexOutOfBoundsException − This exception is thrown if the accessed index/position is out of range.
Getting element of a Vector of Integer by Index Example
The following example shows the usage of Java Vector get(index) method for Integers. We're adding couple of Integers to the Vector object using add() method calls per element and using get(index) method, we're getting one of the element by index and printing it.
package com.tutorialspoint; import java.util.Vector; public class VectorDemo { public static void main(String[] args) { // create an empty array list Vector<Integer> vector = new Vector<>(); // use add() method to add elements in the vector vector.add(20); vector.add(30); vector.add(20); vector.add(30); vector.add(15); vector.add(22); vector.add(11); // let us print the 3rd element System.out.println("3rd Element = " + vector.get(2)); } }
Output
Let us compile and run the above program, this will produce the following result −
3rd Element = 20
Getting element of a Vector of String by Index Example
The following example shows the usage of Java Vector get(index) method for Strings. We're adding couple of Strings to the Vector object using add() method calls per element and using get(index) method, we're getting one of the element by index and printing it.
package com.tutorialspoint; import java.util.Vector; public class VectorDemo { public static void main(String[] args) { // create an empty array list Vector<String> vector = new Vector<>(); // use add() method to add elements in the vector vector.add("Welcome"); vector.add("To"); vector.add("Tutorialspoint"); // let us print the 3rd element System.out.println("3rd Element = " + vector.get(2)); } }
Output
Let us compile and run the above program, this will produce the following result −
3rd Element = Tutorialspoint
Getting element of a Vector of Object by Index Example
The following example shows the usage of Java Vector get(index) method for Student objects. We're adding couple of Student objects to the Vector object using add() method calls per element and using get(index) method, we're getting one of the element by index and printing it.
package com.tutorialspoint; import java.util.Vector; public class VectorDemo { public static void main(String[] args) { // create an empty vector Vector<Student> vector = new Vector<>(); // use add() method to add elements in the vector vector.add(new Student(1, "Julie")); vector.add(new Student(2, "Robert")); vector.add(new Student(3, "Adam")); // let us print the 3rd element System.out.println("3rd Element = " + vector.get(2)); } } class Student { int rollNo; String name; Student(int rollNo, String name){ this.rollNo = rollNo; this.name = name; } @Override public String toString() { return "[ " + this.rollNo + ", " + this.name + " ]"; } }
Output
Let us compile and run the above program, this will produce the following result −
3rd Element = [ 3, Adam ]
