پاسخ عالی
برای اضافه کردن رکورد جدید باید یک متد قرار دهیم و با استفاده از تابع add رکورد را به لیست خود اضافه کنیم.
:UserData.java
@ManagedBean(name = "userData", eager = true)
@SessionScoped
public class UserData implements Serializable {
private static final long serialVersionUID = 1L;
private String name;
private String dept;
private int age;
private double salary;
private static final ArrayList<Employee> employees
= new ArrayList<Employee>(Arrays.asList(
new Employee("John", "Marketing", 30,2000.00),
new Employee("Robert", "Marketing", 35,3000.00),
new Employee("Mark", "Sales", 25,2500.00),
new Employee("Chris", "Marketing", 33,2500.00),
new Employee("Peter", "Customer Care", 20,1500.00)
));
public ArrayList<Employee> getEmployees() {
return employees;
}
public String addEmployee() {
Employee employee = new Employee(name,dept,age,salary);
employees.add(employee);
return null;
}
public String editEmployee(Employee employee) {
employee.setCanEdit(true);
return null;
}
public String saveEmployees() {
for (Employee employee : employees) {
employee.setCanEdit(false);
}
return null;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDepartment() {
return department;
}
public void setDepartment(String department) {
this.department = department;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public double getSalary() {
return salary;
}
public void setSalary(double salary) {
this.salary = salary;
}
