How to Remove Specific Item from a Vector in Java ?

Answer

To remove a specific item from a Vector in Java, you can use the remove method of the java.util.Vector class.

✐ Examples

1 Remove Specific Item Using remove Method

In this example,

We start by importing the necessary class: java.util.Vector.
We create a Vector named vector and initialize it with some integer values.
We specify the item we want to remove and store it in a variable named itemToRemove.
We use the remove method to remove the specified item from the vector. The remove method takes the object to be removed as an argument.
Finally, we print the modified vector to standard output to see the result.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector&lt;Integer&gt; vector = new Vector&lt;&gt;();
        vector.add(10);
        vector.add(20);
        vector.add(30);
        vector.add(40);
        vector.add(50);
        int itemToRemove = 30;
        vector.remove(Integer.valueOf(itemToRemove));
        System.out.println("Vector after removing the item " + itemToRemove + ": " + vector);
    }
}

Output

Vector after removing the item 30: [10, 20, 40, 50]

2 Remove Specific Item Using Iterator

In this example,

We start by importing the necessary class: java.util.Vector.
We create a Vector named vector and initialize it with some integer values.
We specify the item we want to remove and store it in a variable named itemToRemove.
We obtain an iterator for the vector using the iterator method.
We iterate over the vector using the iterator and remove the specified item using the remove method of the iterator.
Finally, we print the modified vector to standard output to see the result.

Java Program

import java.util.Vector;
import java.util.Iterator;

public class Main {
    public static void main(String[] args) {
        Vector&lt;Integer&gt; vector = new Vector&lt;&gt;();
        vector.add(10);
        vector.add(20);
        vector.add(30);
        vector.add(40);
        vector.add(50);
        int itemToRemove = 30;
        Iterator&lt;Integer&gt; iterator = vector.iterator();
        while (iterator.hasNext()) {
            if (iterator.next().equals(itemToRemove)) {
                iterator.remove();
            }
        }
        System.out.println("Vector after removing the item " + itemToRemove + ": " + vector);
    }
}

Output

Vector after removing the item 30: [10, 20, 40, 50]
