How to Remove Specific Element from an Array in Java ?

Answer

To remove a specific element from an array in Java, you can use ArrayList's `remove` method or create a new array excluding the element to be removed.

✐ Examples

1 Remove Element using ArrayList's remove method

In this example,

We create an ArrayList named `numbers` with elements including the one to be removed.
We use the `remove` method of ArrayList to remove the specific element.
Finally, we get an array without the specific element.

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 elementToRemove = 3;
        numbers.remove(Integer.valueOf(elementToRemove));
        System.out.println("Array after removing " + elementToRemove + ": " + numbers);
    }
}

Output

Array after removing 3: [1, 2, 4, 5]

2 Remove Element by creating a new array

In this example,

We create an array named `colors` with elements including the one to be removed.
We iterate through the array and add elements to a new array, excluding the specific element.
Finally, we get an array without the specific element.

Java Program

import java.util.Arrays;

public class Main {
    public static void main(String[] args) {
        String[] colors = {"red", "green", "blue", "yellow"};
        String elementToRemove = "green";
        String[] newArray = new String[colors.length - 1];
        int newIndex = 0;
        for (String color : colors) {
            if (!color.equals(elementToRemove)) {
                newArray[newIndex++] = color;
            }
        }
        System.out.println("Array after removing " + elementToRemove + ": " + Arrays.toString(newArray));
    }
}

Output

Array after removing green: [red, blue, yellow]
