How to Remove Items from Vector based on a Condition in Java - Step by Step Examples

How to Remove Items from Vector based on a Condition in Java ?

Answer

To remove items from a Vector based on a condition in Java, you can iterate over the Vector and remove elements that satisfy the condition.

✐ Examples

1 Remove Items Using Iterator

In this example,

We import the necessary class: java.util.Vector.
We create a Vector named vector and initialize it with some integer values.
We define a condition for removing elements. In this example, we want to remove elements less than 30.
We obtain an iterator for the vector using the iterator method.
We iterate over the vector using the iterator and remove elements that satisfy the condition.
Finally, we print the modified vector 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);
        Iterator&lt;Integer&gt; iterator = vector.iterator();
        while (iterator.hasNext()) {
            int val = iterator.next();
            if (val &lt; 30) {
                iterator.remove();
            }
        }
        System.out.println("Vector after removing items based on condition: " + vector);
    }
}

Output

Vector after removing items based on condition: [30, 40, 50]

2 Remove Items Using for-each Loop

In this example,

We import the necessary class: java.util.Vector.
We create a Vector named vector and initialize it with some integer values.
We define a condition for removing elements. In this example, we want to remove elements less than 30.
We iterate over the vector using a for-each loop and remove elements that satisfy the condition.
Finally, we print the modified vector 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);
        for (Integer val : vector) {
            if (val &lt; 30) {
                vector.remove(val);
            }
        }
        System.out.println("Vector after removing items based on condition: " + vector);
    }
}

Output

Vector after removing items based on condition: [30, 40, 50]
