Question

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.

Apache commons has WordUtils and wrap function in it:

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.
