(9-5)请阅读下面程序,然后写出运行结果。(注意输出不换行)。 class MyException extends Exception { private int x ; MyException( int a ) { x = a ; } public String toString() { return "" + x ; } } public class Demo8 { public static void compute( int a ) throws MyException { System. out .print( a ); if ( a > 10) throw new MyException( a ); System. out .print(99); } public static void main(String args []) { try { compute (6); compute (12); } catch (MyException e ) { System. out .print( e ); } } }
