Question

I’m trying to create a list of float values, but it seems it’s not right this way :
EDIT:

public Supervisory() {
    this.analogs = new ArrayList<Float>();
}

public void active() {
    try {
        for (ObjectIdentifier oi : ois) {

            if (oi.getObjectType().intValue() == 2){
                analogs.add(new Float(10));
            }
        }

    } catch (IOException ioe) {
        throw new RuntimeException(ioe.getMessage());
    } catch (Exception ex) {
        throw new RuntimeException(ex.getMessage());
    }
}

My last code it was just a snippet to give the idea of my problem.

What’s wrong with this implementation ?

Answer 1

You need to put your code inside a method, it cannot just float around in the class:

public class MyClass {
   private List<Float> analogs;

   public void X() {
       this.analogs = new ArrayList<Float>();
       analogs.add(new Float(10));
   }
}

Or in a constructor:

public class MyClass {
   private List<Float> analogs;

   public MyClass() {
       this.analogs = new ArrayList<Float>();
       analogs.add(new Float(10));
   }
}
