Given:
12. String csv = "Sue,5,true,3";
13. Scanner scanner = new Scanner(csv);
14. scanner.useDelimiter(",");
15. int age = scanner.nextInt();
What is the result?
A. Compilation fails.
B. After line 15, the value of age is 5.
C. After line 15, the value of age is 3.
D. An exception is thrown at runtime.
解答
Ans: D
解說:
15. int age = scanner.nextInt();會讀到第一個以逗點隔開的整數， 但是csv第一個是Sue，不是整數，執行時會產生一個例外！
