Consider the following code segment.
int[][] mat = {{10, 15, 20, 25},
{30, 35, 40, 45},
{50, 55, 60, 65}};
for (int[] row : mat)
{
for (int j = 0; j < row.length; j += 2)
{
System.out.print(row[i] + " ");
}
System.out.println();
}
What, if anything, is printed as a result of executing the code segment?

Consider the following code segment int mat 10 15 20 25 30 35 40 45 50 55 60 65 for int row mat for int j 0 j lt rowlength j 2 Systemoutprintrowi Systemoutprint class=

Answer:

10 20                                                                                                                          

30 40                                                                                                                          

50 60

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
