Solid-state drive (SSD) is the commonly used technology these days for hard drives .It has pretty advantages over hard disk drive(HDD) .
One advantage is ,its speed is unmatchable to HDD and the data is stored in microchips. Unlike HDD,which uses a mechanical arm with a read/write head to move around and read information from the right location on a storage platter ,it collects information directly from microchips .It is simply the oversized version of USB stick .More reliable and sustainable.
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
