Write a Java program to create a vector to store integer elements
The code you provided is written in Java and creates a Vector object called vec_list that stores a list of integers. It then adds numbers from 10 to 15 (inclusive) to the vector using a for loop. Finally, it prints the elements of the vector. Here's the explanation of the code step by step:
- import java.util.*;: This line imports the java.util package, which contains the Vector class and other utility classes.
- public class Create_Vector: This line declares a public class named Create_Vector.
- public static void main(String[] args): This is the main method where the execution of the program starts. It takes an array of strings as command line arguments.
- Vector<Integer> vec_list = new Vector<Integer>();: This line declares and initializes a Vector object named vec_list that can store Integer values. Note that using generics (<Integer>) is not necessary in newer versions of Java.
- for (int i = 10; i <= 15; i++): This line starts a for loop with the loop variable i initialized to 10, and it continues as long as i is less than or equal to 15. After each iteration, i is incremented by 1.
- vec_list.add(i); : Inside the for loop, this line adds the value of i to the vector vec_list.
- System.out.println("Vector Elements :" + vec_list);: Finally, this line prints the elements of the vector by concatenating the string "Vector Elements :" with the vector vec_list. The println function automatically converts the vector to a string representation.
Source Code
import java.util.*;
public class Create_Vector
{
public static void main(String[] args)
{
Vector <Integer> vec_list = new Vector <Integer>();
for (int i = 10; i <= 15; i++)
{
vec_list.add(i);
}
System.out.println("Vector Elements :" + vec_list);
}
}
Output
Vector Elements :[10, 11, 12, 13, 14, 15]
