Is Java pass-by-reference?
I am a little confused here. How does Arrays.sort(a) modify the value of a?
int[] a = {9,8,7,6,5,4,3,2,1};
Arrays.sort(a);
System.out.println(Arrays.toString(a));
I thought java was pass by value…
Yes, Java is pass-by-value. However, what is getting passed by value here is the reference to the array, not the array itself.
