How to Split a Vector in Java ?

Answer

In Java, you can split a Vector into smaller parts using various methods such as subList, loops, or by manually copying elements.

✐ Examples

1 Split Vector using subList

In this example,

We create a Vector named vector containing elements.
We use the subList method to obtain a portion of the Vector.
The subList method returns a new List containing elements from the specified inclusive start index to the exclusive end index.
We convert the List back to a Vector if needed.

Java Program

import java.util.*;

class Main {
    public static void main(String[] args) {
        Vector<Integer> vector = new Vector<>(Arrays.asList(1, 2, 3, 4, 5, 6));
        int splitIndex = 3;
        Vector<Integer> left = new Vector<>(vector.subList(0, splitIndex));
        Vector<Integer> right = new Vector<>(vector.subList(splitIndex, vector.size()));
        System.out.println("Left part: " + left);
        System.out.println("Right part: " + right);
    }
}

Output

Left part: [1, 2, 3]
Right part: [4, 5, 6]

2 Split Vector using Loop

In this example,

We create a Vector named vector containing elements.
We define the splitting point and create two new Vectors for the left and right parts.
We iterate through the original Vector and add elements to the left and right Vectors based on the splitting point.

Java Program

import java.util.*;

class Main {
    public static void main(String[] args) {
        Vector<Integer> vector = new Vector<>(Arrays.asList(1, 2, 3, 4, 5, 6));
        int splitIndex = 3;
        Vector<Integer> left = new Vector<>();
        Vector<Integer> right = new Vector<>();
        for (int i = 0; i < vector.size(); i++) {
            if (i < splitIndex) {
                left.add(vector.get(i));
            } else {
                right.add(vector.get(i));
            }
        }
        System.out.println("Left part: " + left);
        System.out.println("Right part: " + right);
    }
}

Output

Left part: [1, 2, 3]
Right part: [4, 5, 6]
