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 ]
