How to Slice a List in Java ?

Answer

To slice a list in Java, you can use the subList method provided by the Java standard library.

✐ Examples

1 Slice a List of Integers

In this example,

We create a list named numbers with integer values.
We use the subList method on the list object numbers to create a new list from index 1 to index 4 (exclusive).
The subList method returns a view of the specified range within the original list.
Finally, we print the sliced list to standard output.

Java Program

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

public class Main {
    public static void main(String[] args) {
        List<Integer> numbers = new ArrayList<>(List.of(1, 2, 3, 4, 5));
        List<Integer> slicedNumbers = numbers.subList(1, 4);
        System.out.println("Sliced list: " + slicedNumbers);
    }
}

Output

Sliced list: [2, 3, 4]

2 Slice a List of Strings

In this example,

We create a list named words with string values.
We use the subList method on the list object words to create a new list from index 2 to index 5 (exclusive).
The subList method returns a view of the specified range within the original list.
Finally, we print the sliced list to standard output.

Java Program

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

public class Main {
    public static void main(String[] args) {
        List<String> words = new ArrayList<>(List.of("apple", "banana", "cherry", "date", "elderberry"));
        List<String> slicedWords = words.subList(2, 5);
        System.out.println("Sliced list: " + slicedWords);
    }
}

Output

Sliced list: [cherry, date, elderberry]
