Explanation:

Given

The above code segment

Required

What is printed, if anything

To do this, we analyze the code line by line.

Line 1: The first line creates a 4 by 3 array named mat

Line 2: for (int[] row : mat) {  -> This creates row[] array which represents each row of array mat

Line 3: for (int j = 0; j < row.length; j += 2){ -> This iterates through the even indexed elements of the row array i.e. 0 and 2

Line 4: System.out.print(row[i] + " "); -> This prints the even indexed elements of the row array.

The even indexed elements are: 10, 20, 30, 40, 50 and 60

Line 5: System.out.println(); --> This prints a new line
