I have a hashmap, and it has example HashMap<string,dog)>

Now the dog has fields like name, size, age ...

I have a couple of check boxes and the user will check the fields to display of the dog. so if checkboxname is selected it will display all the names in the hashmap.

is it possible for starters? btw, hashmap<string... string="" is="" the="" name="" of="" dogs.="" as="" it="" mode="hold">
Tha's what i did so far, but im really stuck.

Java

JCheckBox cbName = new JCheckBox("Name ");
        JCheckBox cbtype = new JCheckBox("Type ");
        JCheckBox cbDistance = new JCheckBox("Distance ");
JTextArea txttextarea = new JTextArea();

        if (cbName.isSelected() == true) {
            for (int i = 0; i <= DataCollection.map.values().size(); i++) {
                txttextarea.add(DataCollection.map.values().contains())
                
            }
        }

Don't make it rocket science.

You know the number of dogs and therefor the number of values to be displayed.
So make your GUI dynamically out of that:

Java

if (cbName.isSelected() == true) {
  foreach (Dog oDog: oDogs){
    if(null != oDog.getName()){
      JCheckBox oCheckbox = new JCheckBox(oDog.getName());
    }
  }
}
