How to get Sub Vector in Java - Step by Step Examples

How to get Sub Vector in Java ?

Answer

To get a sub-vector in Java using java.util.Vector, you can use the subList method.


✐ Examples

1 Get Sub-Vector of Index Range [1, 3)

In this example,

  1. We have a Vector named vec containing elements.
  2. We use the subList method, specifying the starting index (inclusive) and the ending index (exclusive) to obtain a sub-list.
  3. We assign the sub-list to a new Vector named subVec.
  4. Finally, we print the elements of subVec to standard output.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> vec = new Vector<Integer>();
        vec.add(1);
        vec.add(2);
        vec.add(3);
        vec.add(4);
        vec.add(5);
        Vector<Integer> subVec = new Vector<Integer>(vec.subList(1, 3));
        for (int x : subVec) {
            System.out.print(x + " ");
        }
    }
}

Output

2 3

2 Get Sub-Vector of Index Range [1, 5)

In this example,

  1. We have a Vector named vec containing elements.
  2. We use the subList method, specifying the starting index (inclusive) and the ending index (exclusive) to obtain a sub-list.
  3. We assign the sub-list to a new Vector named subVec.
  4. Finally, we print the elements of subVec to standard output.

Java Program

import java.util.Vector;

public class Main {
    public static void main(String[] args) {
        Vector<Integer> vec = new Vector<Integer>();
        vec.add(1);
        vec.add(2);
        vec.add(3);
        vec.add(4);
        vec.add(5);
        Vector<Integer> subVec = new Vector<Integer>(vec.subList(1, 5));
        for (int x : subVec) {
            System.out.print(x + " ");
        }
    }
}

Output

2 3 4 5
