        emp1.setName("Name1");
        emp1.setStreet("Str1");
        emp1.setCity("CA");         
        emp1.setZip("1234");
        empp1.add(emp1);

        Employee2 emp2 = new Employee2();

JavaCode：

    private String city;
    private String zip;
}

public class Employee2 {    
    private String sno;
    private String age;
    private String position;
}

public class Employees1 implements Serializable 
{
private List<Employee1> employee1 = null;
private List<Employee2> employee2 = null;
}
