Java quiz. What is the result of the following code compilati | CodeGalaxy.io

What is the result of the following code compilation and execution?


public class Test {
    public static void main(String[] args) {
        for (final int i : new int[] { 1, 2, 3 }) {
            System.out.println(i + 1);
        }
    }
}

Explanation

This loop is unfolded by the compiler into a code doing this:


array = new int[] { 1, 2, 3 };
for(int index = 0; index < array.length; index
++) {
final int i = array[index];
...
}

i is a local variable, which, as expected, is initialized at the beginning of each iteration of the loop.
