How to Remove Element at a Specific Index from a List in Java ?

Answer

To remove an element at a specific index from a list in Java, you can use the remove method.

✐ Examples

1 Remove Element at Specific Index

In this example,

We create an ArrayList named numbers with integer values.
We use the remove method of the ArrayList to remove the element at the specified index.
Finally, we print the modified ArrayList to standard output.

Java Program

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> numbers = new ArrayList<>();
        numbers.add(1);
        numbers.add(2);
        numbers.add(3);
        numbers.add(4);
        numbers.add(5);
        int indexToRemove = 2;
        numbers.remove(indexToRemove);
        System.out.println("ArrayList after removing element at index " + indexToRemove + ": " + numbers);
    }
}

Output

ArrayList after removing element at index 2: [1, 2, 4, 5]

2 Remove Element at First Index

In this example,

We create an ArrayList named words with string values.
We use the remove method of the ArrayList to remove the element at the first index.
Finally, we print the modified ArrayList to standard output.

Java Program

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<String> words = new ArrayList<>();
        words.add("apple");
        words.add("banana");
        words.add("cherry");
        words.remove(0);
        System.out.println("ArrayList after removing element at first index: " + words);
    }
}

Output

ArrayList after removing element at first index: [banana, cherry]
