QUESTION 49 

Given: 

 

1. public class Pass { 

2.     public static void main(String [] args) { 

3.         int x = 5; 

4.         Pass p = new Pass(); 

5.         p.doStuff(x); 

6.         System.out.print(" main x = " + x); 

7.     } 

8.  

9.     void doStuff(int x) { 

10.         System.out.print(" doStuff x = " + x++); 

11.     } 

12. } 

 

What is the result? 

 

A. Compilation fails. 

B. An exception is thrown at runtime. 

C. doStuff x = 6 main x = 6 

D. doStuff x = 5 main x = 5 

E. doStuff x = 5 main x = 6 

F. doStuff x = 6 main x = 5 

Solution : D 

초기 x 값 5 --> doStuff x = 5 출력 --> main 문으로 다시 돌아와서 main x = 5
