How to Filter Items of a Vector based on a Condition in Java ?

Answer

To filter items of a Vector based on a condition in Java using java.util.Vector, you can iterate through the Vector and remove elements that do not meet the condition.

✐ Examples

1 Filter Items Greater Than a Threshold

In this example,

First, you create a Vector containing the elements you want to filter.
Next, you specify the condition for filtering, such as greater than a threshold.
Then, you iterate through the Vector using a ListIterator and remove elements that do not meet the condition.

Java Program

import java.util.Vector;
import java.util.ListIterator;

public class Main {
    public static void main(String[] args) {
        // Create a Vector containing elements
        Vector<Integer> vector = new Vector<>();
        vector.add(1);
        vector.add(5);
        vector.add(10);
        vector.add(15);
        vector.add(20);

        // Specify the threshold for filtering
        int threshold = 10;

        // Iterate through the Vector and remove elements greater than the threshold
        ListIterator<Integer> iterator = vector.listIterator();
        while (iterator.hasNext()) {
            if (iterator.next() <= threshold) {
                iterator.remove();
            }
        }

        // Print the filtered Vector
        System.out.println(vector);
    }
}

2 Filter Items Meeting a Condition

In this example,

Create a Vector containing elements.
Specify the condition for filtering.
Iterate through the Vector using a ListIterator and remove elements that do not meet the condition.

Java Program

import java.util.Vector;
import java.util.ListIterator;

public class Main {
    public static void main(String[] args) {
        // Create a Vector containing elements
        Vector<Integer> vector = new Vector<>();
        vector.add(1);
        vector.add(5);
        vector.add(10);
        vector.add(15);
        vector.add(20);

        // Specify the condition for filtering
        // Select even numbers

        // Iterate through the Vector and remove elements not meeting the condition
        ListIterator<Integer> iterator = vector.listIterator();
        while (iterator.hasNext()) {
            if (iterator.next() % 2 != 0) {
                iterator.remove();
            }
        }

        // Print the filtered Vector
        System.out.println(vector);
    }
}
