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]
