Java Tutorial : Java Array (User Defined Object) 

Employee.java
public class Employee
{

    private String name;
    private int age;
    private int salary;

    public Employee(String name, int age, int salary)
    {
        super();
        this.name = name;
        this.age = age;
        this.salary = salary;
    }

    public String getName()
    {
        return name;
    }

    public void setName(String name)
    {
        this.name = name;
    }

    public int getAge()
    {
        return age;
    }

    public void setAge(int age)
    {
        this.age = age;
    }

    public int getSalary()
    {
        return salary;
    }

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

    @Override
    public String toString()
    {
        return "Employee [name=" + name + ", age=" + age + ", salary=" + salary
                + "]";
    }

}
ArrayDemo.java
class ArrayDemo
{
    public static void main(String[] args)
    {
        /*
         * declares an array of Employee Objects and allocates memory for 5
         * Employee Objects
         */
        Employee[] employeeArray = new Employee[5];

        // initialize first element
        employeeArray[0] = new Employee("Peter", 23, 60000);
        // initialize second element
        employeeArray[1] = new Employee("John", 33, 66000);
        // and so forth
        employeeArray[2] = new Employee("Ram", 31, 90000);
        employeeArray[3] = new Employee("David", 24, 40000);
        employeeArray[4] = new Employee("Stephan", 45, 95000);

        int i = 0;
        for (Employee employee : employeeArray)
        {
            System.out.println("Element at index " + i + " : " + employee);
            ++i;
        }

    }
}
Output
Element at index 0 : Employee [name=Peter, age=23, salary=60000]
Element at index 1 : Employee [name=John, age=33, salary=66000]
Element at index 2 : Employee [name=Ram, age=31, salary=90000]
Element at index 3 : Employee [name=David, age=24, salary=40000]
Element at index 4 : Employee [name=Stephan, age=45, salary=95000]
