請閱讀並執行AboutException.java示例,
import javax.swing.*; class AboutException { public static void main(String[] a) { int i=1, j=0, k; k=i/j; try { k = i/j; // Causes division-by-zero exception //throw new Exception("Hello.Exception!"); } catch ( ArithmeticException e) { System.out.println("被0除. "+ e.getMessage()); } catch (Exception e) { if (e instanceof ArithmeticException) System.out.println("被0除"); else { System.out.println(e.getMessage()); } } finally { JOptionPane.showConfirmDialog(null,"OK"); } } }
