ArrayListExample.java

import java.util.ArrayList;
import java.util.List;

/*
 * Storing user-defined class objects.
 */
public class ArrayListExample
{

    public static void main(String[] args)
    {
        List<Employee> list = new ArrayList<Employee>();

        Employee john = new Employee("John", 32, 40000);
        Employee david = new Employee("David", 42, 80000);
        Employee peter = new Employee("Peter", 52, 150000);

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

        /*
         * Using for each loop getting each employee object from the list
         */
        for (Employee employee : list)
        {
            System.out.println(employee.toString());
        }
    }
}

Output

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