Java uses the available fonts, styles, font sizes to decorate text

(1) Function Description:
Glyph class font is used to standardize the font size, style, and font used by the component. Its constructors:
Public Font (String name,int style,int size);
Name indicates a locally available font name
Style represents the font style, containing three font.plain,font.bold,font.italic, corresponding to the flat, bold, and italic respectively.

A useful way to get locally available fonts
Graphicsenvironment ge=graphicsenvironment.getlocalgraphicsenvironment ();
String[] Fa=ge.getavailablefontfamilynames ();

Array groups are obtained from the drawing environment to locally available fonts.

(2) The code displays the word on the form with the specified font constraint.
