如果不存在Hello.txt文件,那么运行以下程序代码的输出结果是: import java.io.*; pubic class Test{ public static void main(String args[]){ Test t = new Test(); System.out.print(t.methodA()); } public int methodA(){ try{ FileInputStream dis = new FileInputStream("Hello.txt"); } catch(FileNotFoundException fne){ System.out.print("No such file found;"); return -1; } catch(IOException ioe) { }finally{ System.out.print("Doing finally;"); } return 0; } }
