Salut!

Je te laisse adapter.

Va voir la Javadoc de StreamTokenizer.

	try {
		String filePath = "D:/Normal.dot";
		StreamTokenizer st = new StreamTokenizer(new BufferedReader(new FileReader(filePath)));
		int i;
		while((i=st.nextToken())!=StreamTokenizer.TT_EOF){
			switch(st.ttype){
			case StreamTokenizer.TT_NUMBER:
				System.out.println("Number found: "+st.nval);
				break;
			case StreamTokenizer.TT_WORD:
				System.out.println("Word found: "+st.sval);
				break;
			default:
				System.out.println("Nor number nor word: "+i);
			}
			System.out.println(i);
		}
	} catch (Exception e) {
		e.printStackTrace();
	}
