Java code for wrapping text lines to a max line width

Before I re-invent the wheel (poorly), I'd like to know if there is a some existing Java code for wrapping text lines to a given maximum width. Ideally it would:

  • respect existing linebreaks
  • break up lines that exceed a maximum length on word boundaries
  • break up words whose length exceeds the maximum line width by inserting hyphens

Edit: there are no "pixels" here, only java.lang.String. "maximum width" refers to the number of characters on a line.

Solution

  • Apache commons has WordUtils and wrap function in it:

    http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/text/WordUtils.html

    P.S. Looks like this is deprecated and you need to use

    https://commons.apache.org/proper/commons-text/javadocs/api-release/org/apache/commons/text/WordUtils.html

    instead.
