I searched through many posts and figured out that JLabel supports HTML. So I can do 

JLabel search  = new JLabel(\"Search

    Non-breaking spaces ( ) are supported:

    new JLabel("<html>Search<br/>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; By:</html>");

    If you want to have real right-alignment, use individual right-aligned labels and combine them:

    JLabel search = new JLabel("Search", SwingConstants.RIGHT);
JLabel by = new JLabel("By:", SwingConstants.RIGHT);

JPanel combined = new JPanel();
combined.setOpaque(false);
combined.setLayout(new GridLayout(2, 1));
combined.add(search);
combined.add(by);

    or use a read-only JTextPane instead (with \n for line breaks):

    JTextPane text = new JTextPane();

SimpleAttributeSet attributes = new SimpleAttributeSet();
StyleConstants.setAlignment(attributes, StyleConstants.ALIGN_RIGHT);
StyleConstants.setFontFamily(attributes, "Default");
text.setParagraphAttributes(attributes, true);
text.setEditable(false);
text.setOpaque(false);
text.setText("Search\nBy:");

    There are a number of ways you might achieve this, one of the safer ways might be to use a <table> and aligning both cells to the right...

    Label wrapped in table

    JLabel label = new JLabel(
                "<html><table border='0' cellpadding='0' cellspacing='0'>" + 
                                "<tr><td align='right'>Search</td></tr>" +
                                "<tr><td align='right'>By:</td></tr></table>"
);

    This overcomes issues with differences between fonts and font rendering on different platforms

    Slightly simpler HTML than seen in @MadProgrammer's answer:

    new JLabel("<html><body style='text-align: right'>Search<br>By:");
