如何通过GUI组合框（NetBeans）将项目添加到Java文本文件

Question

I have already defined the items in the combo box inside gui. What happens is that im trying to add an entry to the program text file and it says: incompatible types int cannot be converted to string. I am having problems with setLocation and setSkills .

private void buttonAddActionPerformed(java.awt.event.ActionEvent evt)
{                                          

   Resort p = new Resort();
   p.setName(nameTextField.getText().replaceAll("[^a-z.]", ""));
   p.setLocation(comboResortLocation.getSelectedIndex());
   p.setSkillsByIndex(comboResortSkill.getSelectedIndex());
   txtfile.addResort(p);

   AddedConfirm confirmed = new AddedConfirm();
   confirmed.setVisible(true);
   this.setVisible(false);
}                                    

And the part of the code from the other file.

public void setSkillsByIndex (String skills)
{
    this.skills = skills;            
}        

Answer 1

Got it fixed already. I just had to change them to Strings and use getSelectedItem instead:

   p.setLocationByIndex((String) comboResortLocation.getSelectedItem());

   p.setSkillsByIndex((String) comboResortSkill.getSelectedItem());

and the other file:

public void setLocationByIndex (String location) { this.location = location;

    }        

public void setSkillsByIndex (String skills) { this.skills = skills;

    }
