I dont get it. The constructor in my c

Answer 1

do you mean

public class labelsAndIcons extends JFrame {
    public labelsAndIcons ()
    {
        super( "Testing JLabel" );
    }
}

Answer 2

The constructors name must be the same as the class name. Let's look at this:

constructor call must be the first statement in a constructor  

The constructor word in constructor call references the super class's constructor which is the super();

The constructor word in in a constructor refers to your class's consucor that is : public labelsAndIcons()

so you need to narrow your code to this:

public class labelsAndIcons extends JFrame
{
  public labelsAndIcons ()
  {
     super( "Testing JLabel" );
  }
}

Answer 3

The constructors name must be the same as the class name, so change either change the class name to labelFrame or the constructor name to labelsAndIcons.

Example (note that usually the first letter is a capital letter in java):

public class LabelFrame extends JFrame {
    public LabelFrame() {
        super( "Testing JLabel" );
    }
}

Answer 4

Ideally your code should fail saying Invalid Method declartion because public labelFrame()

• is neither a constructor (because constructor has the same name as the class name).
• is neither proper method declaration.

Whatever change your code like this:

public class labelsAndIcons extends JFrame
{
  public labelsAndIcons ()
  {
     super( "Testing JLabel" );
  }
}
