问题 Hello I am creating a Swing application to create a word document. I have made use of the Apache POI Java API for this purpose. But the problem is --> How do I set the word document to be read only after creation? I have heard of java.io.File.setReadOnly() method, but I don't know how to use it in this context.

问题 I'm having a little trouble with setting a custom font color for an XSSFWorkbook from Apache POI . When I do: yellow = workbook.createCellStyle(); Font whiteFont = workbook.createFont(); whiteFont.setColor(new XSSFColor(new Color(255, 255, 255)).getIndexed()); yellow.setFillForegroundColor(new XSSFColor(yellowRGB)); yellow.setFillPattern(XSSFCellStyle.SOLID_FOREGROUND); yellow.setFont(whiteFont); The font stays black, I'm not sure what I'm doing wrong though. 回答1: You can do whiteFont

问题 I'm using Apache POI 3.16 (the latest version at the time of writing).
