Help with the CheckBox button in JTable

.............................

Quote:

While the user checked the checkbox, it will not appear that row on the next Run.

I have no idea what you mean by: "appear that row on the next run". Can you explain what is happening because I am unclear.

Code java:

class StockEnquiryStaff implements Comparable {
public String name;
public String telephone;
public String callback;
public String enquiry;
public Boolean check;
 
public StockEnquiryStaff(String n, String t, String c, String e, Boolean ck){
this.name = n;
this.telephone = t;
this.callback = c;
this.enquiry = e;
this.check = ck;
}
 
public String getName() {
return name;
}
public String getTelephone() {
return telephone;
}
public String getCallback() {
return callback;
}
public String getEnquiry() {
return enquiry;
}
public Boolean getCheck() {
return check;
}
public int compareTo(Object o) {
StockEnquiryStaff temp = (StockEnquiryStaff) o;
return (callback.compareTo(temp.callback));
}
}

Looks like it's reading a name, a number, and a time.
