多项选择题 现有: class Flow { public static void main(String [] args) try { System. out .print ("before") ; doRiskyThing ( ) ; System.out.print ("after ") ; } catch (Exception fe) { System.out.print ("catch") ; } System. out .println ( " done") ; } public static void doRiskyThing() throws Exception{ // this code returns unless it throws an Exception }} 可能会产生哪两项结果 ?()
多项选择题 现有 1. class Calc { 2. public static void main(String [] args) { 3. try { 4. int x = Integer.parselnt ("42a") ; 5. //insert code here 6. System.out.print ("oops"); 7. } 8. } 9. } 下面哪两行分别插入到第五行,会导致输 "oops" ? ()
单项选择题 现有: void topGo() { try { middleGo(); } catch (Exception e) { System.out.print("catch"); } } void middleGo() throws Exception { go(); system.out.print("late middle"); } void go() throws ExceptiOn { throw new Exception(); } 如果调用 topGo () ,则结果为:()
