Question

How can I make the text of a JLabel extend onto another line

This is horrifying  All these answers suggesting  adding  to the start of the label text  and there is not one word in the Java 11  or earlier  documentation for JLabel to suggest that the text of a label is handled differently if it happens to start with  lt html gt   Who says that works everywhere and always will  And you can get big  big surprises wrapping arbitrary text in  and handing it to an html layout engine    I ve upvoted the answer that suggests JTextArea  But I ll note that JTextArea isn t a drop-in replacement  by default it expands to fill rows  which is not how JLabel acts  I haven t come up with a solution to that yet

Type the content  i e   the  text  property field  inside a  lt html gt  lt  html gt  tag  So you can use  lt br gt  or lt P gt  to insert a newline   For example   String labelContent     lt html gt Twinkle  twinkle  little star  lt BR gt How I wonder what you are  lt BR gt Up above the world so high  lt BR gt Like a diamond in the sky  lt  html gt      It will display as follows   Twinkle  twinkle  little star  How I wonder what you are  Up above the world so high  Like a diamond in the sky
