在J2EE中,如果去編譯并運行下面的代碼,在這里假定在當(dāng)前目錄下沒有Hello.txt文件: import java.io.*; public class Mine { public static void main(String argv[]){ Mine m=new Mine(); System.out.println(m.amethod()); } public int amethod() { try { FileInputStream dis=new FileInputStream("Hello.txt"); } catch (FileNotFoundException fne) { System.out.println("No such file found"); return -1; } catch(IOException ioe) { } finally { System.out.println("Doing finally"); } return 0; } } 結(jié)果會輸出()。
