Vector subList() Method in Java

The java.util.Vector.subList() is used to return a sublist of the existing Vector within a range mentioned in the parameter. The method takes in an upper limit and a lower limit and returns all the elements mentioned in the range. The lower limit is included if the element is present in the list and the upper limit is excluded. Basically, it takes the sublist greater than equal to the lower limit and strictly less than the upper element.

Syntax:

Vector.subList(int low_index, int up_index)

Parameters: The method accepts 2 mandatory parameters: 

• low_index: This is of the integer type and defines the lower limit or the index of the starting element from which the subList is evaluated. This element is included in the sublist.
• up_index: This is of the integer type and defines the upper limit or the index of the end element till which the subList is evaluated. This element is excluded from the sublist.

Return Value: The method returns a sublist of the Vector type mentioned within the given range of the parameters.

Example 1:

Java

// Java Program to illustrate subList() method
// of Vector class

// Importing required class
import java.util.*;

// Main class
public class GFG {

    // Main driver method
    public static void main(String[] args)
    {
        // Creating an empty Vector by declaring
        // object of Vector class of Integer type
        Vector<Integer> vec_tor = new Vector<Integer>();

        // Adding custom input elements
        // using add() method
        vec_tor.add(5);
        vec_tor.add(1);
        vec_tor.add(50);
        vec_tor.add(10);
        vec_tor.add(20);
        vec_tor.add(6);
        vec_tor.add(20);
        vec_tor.add(18);
        vec_tor.add(9);
        vec_tor.add(30);

        // Print and display all elements present in vector
        System.out.println("The Vector is: " + vec_tor);

        // Creating the sublist vector
        List<Integer> sub_list = new ArrayList<Integer>();

        // Limiting the values till 5
        // using subList() method via passing arguments
        sub_list = vec_tor.subList(2, 5);

        // Displaying the elements present inside list
        System.out.println("The resultant values "
                           + "within the sub list: "
                           + sub_list);
    }
}

Output:

The Vector is: [5, 1, 50, 10, 20, 6, 20, 18, 9, 30]
The resultant values within the sub list: [50, 10, 20]

Example 2:

Java

// Java Program to illustrate subList() method
// of Vector class

// Importing required class
import java.util.*;

// Main class
public class GFG {

    // Main driver method
    public static void main(String[] args)
    {
        // Creating an empty Vector by
        // creating string object of Vector class
        Vector<String> vec_tor = new Vector<String>();

        // Adding custom input elements to above vector
        // object using add() method
        vec_tor.add("Welcome");
        vec_tor.add("To");
        vec_tor.add("Geek");
        vec_tor.add("For");
        vec_tor.add("Geeks");

        // Display message only
        System.out.println("The Vector is: " + vec_tor);

        // Creating the sublist vector
        List<String> sub_list = new ArrayList<String>();

        // Limiting the values till 5
        // using subList() method
        sub_list = vec_tor.subList(1, 5);

        // Display elements of List object
        System.out.println("The resultant values "
                           + "within the sub list: "
                           + sub_list);
    }
}

Output

The Vector is: [Welcome, To, Geek, For, Geeks]
The resultant values within the sub list: [To, Geek, For, Geeks]
