How to Remove Specific Element from a List in Java ?

Answer

To remove a specific element from a list in Java using `java.util.ArrayList`, you can use the `remove` method.

✐ Examples

1 Remove Element Present in the List

In this example,

We create an ArrayList named list with some elements.
We specify the value of the element we want to remove.
We use the remove method of the list to remove the element if it is present.
If the element is found and removed, the list is modified accordingly.
Finally, we print the modified list to standard output.

Java Program

import java.util.ArrayList;

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

Output

Modified list after removing 3: [1, 2, 4, 5]

2 Remove Element Not Present in the List

In this example,

We create an ArrayList named list with some elements.
We specify the value of an element that is not present in the list.
We use the remove method of the list to attempt to remove the element.
Since the element is not present, the list remains unchanged.
Finally, we print the original list to standard output.

Java Program

import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<Integer> list = new ArrayList<>();
        list.add(1);
        list.add(2);
        list.add(3);
        list.add(4);
        list.add(5);
        int elementToRemove = 6;
        list.remove(Integer.valueOf(elementToRemove));
        System.out.println("Original list: " + list);
    }
}

Output

Original list: [1, 2, 3, 4, 5]
