The subList() method returns a view of the portion of a list between the specified fromIndex, inclusive, and toIndex, exclusive. The changes in a sublist are reflected in the original list.

Java ArrayList subList() Example

import java.util.ArrayList;
import java.util.List;

public class SubListEx {

    public static void main(String[] args) {
        
        List<String> items = new ArrayList<>();

        items.add("coin");
        items.add("pen");
        items.add("cup");
        items.add("notebook");
        items.add("glass");
        items.add("chair");
        items.add("ball");
        items.add("bowl");
        
        List<String> items2 = items.subList(2, 5);
        
        System.out.println(items2);
        
        items2.set(0, "bottle");
        
        System.out.println(items2);
        System.out.println(items);
    }
}

Output

[cup, notebook, glass]
[bottle, notebook, glass]
[coin, pen, bottle, notebook, glass, chair, ball, bowl]
