    }

    public int getSalary()
    {

    }

    public void setSalary( int salary )
    {
        this.salary = salary;

    @Override

    {
        return "Employee [name=" + name + ", age=" + age + ", salary=" + salary
                + "]";
    }

}

VectorExample.java

import java.util.Vector;
/*
 * Storing user-defined class objects.
 */
public class VectorExample
{
    public static void main( String[] args )
    {
        Vector<Employee> vector = new Vector<Employee>();
        
        Employee john = new Employee("John", 32, 40000);
        Employee david = new Employee("David", 42, 80000);
        Employee peter = new Employee("Peter", 52, 150000);


        vector.add(john);
        vector.add(david);
        vector.add(peter);
        

        System.out.println("vector  : " + vector);
        System.out.println("----------------------------------------\n");
        
        /*
         * Using for each loop getting each employee object from the vector
         */
        for( Employee employee : vector )
        {
            System.out.println("Name : "+employee.getName());
            System.out.println("Age :"+employee.getAge());
            System.out.println("Salary :"+employee.getSalary());
            System.out.println("----------------------------------------");
        }


    }
}

Output

vector  : [Employee [name=John, age=32, salary=40000], Employee [name=David, age=42, salary=80000], Employee [name=Peter, age=52, salary=150000]]
