Fragen zum Laden von Fonts

[Luk10]

Grüße,

Ich muss mich gerade mit Fonts beschäftigen und hätte einige Fragen dazu. Das Oracle Tutorial ist leider von 1998 ... bin mir nicht ganz sicher ob das noch so aktuell ist.

1. Gibt es Fonts, die auf jedem OS vorinstalliert sind, und wenn ja welche?
2. Wie kann ich neue Fonts aus eine .ttf laden?

Danke,

Anschließende Frage:

				try {
				
					g.setFont(Font.createFont(Font.TRUETYPE_FONT, new FileInputStream(("/_ttf/LinLibertine_R.ttf"))));
				
				} catch (Exception e) {
					
					e.printStackTrace();
					
				}

Wirft mir diese Exception:

java.io.FileNotFoundException: \_ttf\LinLibertine_R.ttf (Das System kann den angegebenen Pfad nicht finden)

Will die Datei aus meiner Referenced Library (in Eclipse) laden. Pfad ist okay, habe ich überprüft. Wieso bekomme ich diese Exception?

EDIT:

				Font font = null;
				try {
					
					InputStream is = this.getClass().getResourceAsStream(("/_ttf/LinLibertine_R.ttf"));
					font = Font.createFont(Font.TRUETYPE_FONT, is);
					is.close();
				
				} catch (Exception e) {
					
					e.printStackTrace();
					
				}

Funktioniert. Wieso weiß ich nicht.

Weil

new FileInputStream(("/_ttf/LinLibertine_R.ttf"))

dies vom Dateisystem lädt, und zwar relativ zum aktuellen Arbeitsverzeichnis.

InputStream is = this.getClass().getResourceAsStream(("/_ttf/LinLibertine_R.ttf"));

Dies lädt über den Classloader aus den Resourcen deines Projekts (aus dem eigenen JAR).
