You can do  JLabel l   new JLabel   lt html gt  lt p gt Hello World  blah blah blah lt  p gt  lt  html gt    SwingConstants CENTER     and it will automatically wrap it where appropriate

You can use the MultilineLabel component in the Jide Open Source Components   http   www jidesoft com products oss htm

You can try and do this   myLabel setText   lt html gt     myString replaceAll   lt     amp lt    replaceAll   gt      amp gt    replaceAll   n     lt br  gt        lt  html gt      The advantages of doing this are    It replaces all newlines with  lt br  gt   without fail  It automatically replaces eventual  lt  and  gt  with  amp lt  and  amp gt  respectively  preventing some render havoc    What it does is      lt html gt     adds an opening html tag at the beginning  replaceAll   lt      amp lt    replaceAll   gt      amp gt    escapes  lt  and  gt  for convenience  replaceAll   n     lt br  gt    replaces all newlines by br  HTML line break  tags for what you wanted     and     lt  html gt   closes our html tag at the end    P S   I m very sorry to wake up such an old post  but whatever  you have a reliable snippet for your Java

JLabel is actually capable of displaying some rudimentary HTML  which is why it is not responding to your use of the newline character  unlike  say  System out    If you put in the corresponding HTML and used  lt BR gt   you would get your newlines

Thanks Aakash for recommending JIDE MultilineLabel  JIDE s StyledLabel is also enhanced recently to support multiple line  I would recommend it over the MultilineLabel as it has many other great features  You can check out an article on StyledLabel below  It is still free and open source   http   www jidesoft com articles StyledLabel pdf

Surround the string with  lt html gt  lt  html gt  and break the lines with  lt br  gt    JLabel l   new JLabel   lt html gt Hello World  lt br  gt blahblahblah lt  html gt    SwingConstants CENTER
