Explanation / Answer

before calling changeValues

a1 a2 a3

111 222 333

before changing the values

f1 f2 f3

111 222 333

after changing the values

f1 f2 f3

999 888 777

after calling changeValues

a1 a2 a3

111 888 777

here a1 is primitive and a2 and a3 are the reference variables so the values

whatever we change changeValues function will effect to a2 and a3 not for a1
