我有工作要做，我想在我的GUI中显示这个程序的结果，但我不能这样做，然后我想要一个方法让我在我的图表inetreface中看到这个程序的结果，所以我创建了一个界面，我保留了一个按钮显示和一个显示区域（JTextArea），这意味着当我点击按钮显示我显示结果（我的Rdf文件的内容）。如果可能，我希望得到你的帮助，并提前感谢你
Model model = ModelFactory.createDefaultModel();
// use the FileManager to find the input file
InputStream in = (InputStream) FileManager.get().open("C:/Users/SAMSUNG/Desktop/WICM2/projet/opus_august2007.rdf");
if (in == null) {
throw new IllegalArgumentException(
"File: " + "C:/Users/SAMSUNG/Desktop/WICM2/projet/opus_august2007.rdf"+ " not found");
}
// read the RDF/XML file
model.read(in, "");
// write it to standard out
//model.write(System.out);
model.write(System.out);
这是我的程序界面

如果我了解您想在文本区域中显示整个RDF文件。所以如果它就是你想要的东西，你只需要使用类似......的读者来阅读它。
try{
FileReader f = new FileReader("c:\\opus_august2007.rdf");
BufferedReader b = new BufferedReader(f);
boolean eof = false;
while(! eof)
{
String lineIn = b.readLine();
if(lineIn == null)
{
eof = true;
}
else
{
mytxtarea.append(lineIn + System.getProperty("line.separator"));
}
}
}catch(Exception e){
e.printStackTrace();
}
