Array initialisation in java

Question

I noticed one could write code like this, which is perfectly normal, by the way:

int arrays[] = {1, 2, 3};
for (int n : arrays)
   System.out.println(n);
         


        

Answer 1

You need this syntax:

for(int n : new int[]{1, 2, 3})
   System.out.println(n);
