Given:
11. class Converter{
12. public static void main(String[] args){
13. Integer i = args[0];
14. int j = 12;
15. System.out.println("It is " + (j==i) + " that j==i.");
16. }
17. }
What is the result when the programmer attempts to compile the code and run it with the command
java Converter 12?
A. It is true that j==i.
B. It is false that j==i.
C. An exception is thrown at runtime.
D. Compilation fails because of an error in line 13.
答案：D
參考：8-4 main()方法的參數傳遞與系統屬性設定

args 是 String, 所以不能指派給 Integer.
