List sublist() Method in Java with Examples

This method gives a view of the portion of this list between the specified fromIndex, inclusive, and toIndex, exclusive.

Syntax:

List subList(int fromIndex,
              int toIndex)

Parameters: This function has two parameter fromIndex and toIndex, which are the starting and ending ranges respectively to create a sublist form the given list.

Returns: This method returns the view of list between the given ranges.

Below programs show the implementation of this method.

Program 1:

// Java code to show the implementation of
// lastIndexOf method in list interface
import java.util.*;
public class GfG {

    // Driver code
    public static void main(String[] args)
    {

        // Initializing a list of type Linkedlist
        List<Integer> l = new LinkedList<>();
        l.add(1);
        l.add(3);
        l.add(5);
        l.add(7);
        l.add(3);
        System.out.println(l);
        System.out.println(l.lastIndexOf(3));
    }
}

Output:

[1, 3, 5, 7, 3]
4

Output:

[1, 3, 5, 7, 3]
4

Program 2: Below is the code to show implementation of list.subList() using Linkedlist.

// Java code to show the implementation of
// subList method in list interface
import java.util.*;
public class GfG {

    // Driver code
    public static void main(String[] args)
    {

        // Initializing a list of type Linkedlist
        List<Integer> l = new LinkedList<>();
        l.add(10);
        l.add(30);
        l.add(50);
        l.add(70);
        l.add(30);
        List<Integer> sub = new LinkedList<>();
        System.out.println(l);
        sub = l.subList(1, 3);
        System.out.println(sub);
    }
}

Output:

[10, 30, 50, 70, 30]
[30, 50]
