How to display checkbox that retrieve value from database?

Question

Hi,
I have a problem, hope someone will help me.
The problem is, I have 3 checkbox where contain different values.
I will insert the values to db in array. When I retrieve the values, I got a problem to display it.
Let say,my checkbox's value is:
1.car
2.bus
3.lorry
when I checked car and lorry, my array will be [car,bus] insert to db.
For editing purpose, I need to display the checkbox again with the values from db. So, it should be :
1.car (checked)
2.bus (checked)
3.lorry (unchecked)
I can display the car and bus (checked) , but not the unchecked checkbox. Sometimes, it's repeating, car (checked) and car (unchecked) will display.
Anybody have a suggestion?
My codes:
String[] list = {"car","bus","lorry"};
String[] logtype ={"car","bus"}//retrieve from db (example)
for (int i=0;i<logtype.length;i++){
if (logtype.equals(list[i]){
<input type="checkbox" name="type" value="<%=list[i]%>" checked>
else{
<input type="checkbox" name="type" value="<%=list[i]%>" >

hey u can solve this problem by using vector instead of array
here's the code
<%
Vector list=new Vector();
list.addElement("car");
list.addElement("bus");
list.addElement("lorry");
Vector logtype=new Vector();
logtype.addElement("car");
logtype.addElement("bus");
for(int i=0;i<list.size();i++)
     if(logtype.contains(list.elementAt(i)))
     { %>
          <%=list.elementAt(i)%><input type="checkbox" name="type" value="<%=list.elementAt(i)%>" checked>
     <%}
     else
     {%>
          <%=list.elementAt(i)%><input type="checkbox" name="type" value="<%=list.elementAt(i)%>" >
     <%}
%>
