All that the JLabel.LEFT in the constructor does is to tell the label to left-align it's contents. Depending on how the label is laid out in it's container this may or may not make a difference. (i.e. - if the label itself is only the size of the text, then it won't look any different. If the label itself is larger than the text, then the text will shift to the left.)
Check the size your label is in the layout of it's container - an easy way to see this is to set a border on your label.
