Java OCA OCP Practice Question 951

Question

Which of the following compile? (Choose all that apply) 

A. public void methodA(int... nums) {} 
B. public void methodB(String values, int... nums) {} 
C. public void methodC(int... nums, String values) {} 
D. public void methodD(String... values, int... nums) {} 
E. public void methodE(String[] values, ...int nums) {} 
F. public void methodF(String... values, int[] nums) {} 
G. public void methodG(String[] values, int[] nums) {} 



A, B, G.

Note

Options A and B are correct because the single vararg parameter is the last parameter declared.

Option G is correct because it doesn't use any vararg parameters at all.

Options C and F are incorrect because the vararg parameter is not last.

Option D is incorrect because two vararg parameters are not allowed in the same method.

Option E is incorrect because the ... for a vararg must be after the type, not before it.
