I have an arraylist of city names and I want to show them as a bottom up jlabels. How can I do that?
ArrayList<String> cityNames = new ArrayList<>(columnCount);
while(resultSet.next()){
int i = 1;
while(i <= columnCount) {
cityNames.add(resultSet.getString(i++));
}
}
//Loop through cityNames as seperate Jlabels
for(String city : cityNames){
cityLabel.setText(city);
}
To create multiple JLabel
s and add them to a panel
JPanel panel = [...];
ArrayList<String> cityNames = [...];
for(String city : cityNames)
panel.add(new JLabel(city));
If you need to do something with them later, add them to a List
as well
JPanel panel = [...];
ArrayList<String> cityNames = [...];
List<JLabel> cityLabels = new ArrayList<JLabel>();
for(String city : cityNames)
{
JLabel label = new JLabel(city);
cityLabels.add(label);
panel.add(label);
}
If you just want all of the city names in one JLabel
(can be on multiple lines)
ArrayList<String> cityNames = [...];
String cities = "";
for(String city : cityNames)
cities += ", " + city; //or use "<br>" for separate lines
cities = cities.substring(2); //remove the first ", "
JLabel cityLabel = new JLabel(cities); //add this to your rendering panel
