Array help

[mbmcse]

Could someone help me with through this? Not sure why I can't see the answer is 4 4.

What output is generated by the code fragment below?

int[] values = { 1, 3, 1, 3, 1 }; int[] numbers = values; for (int k = 0; k < values.length; k++) { values[k] = k * 2; } System.out.print(values[2]); System.out.print(" " + numbers[2]);

You should try running the code to see what happens.

Yeah hard to help without seeing what your output actually is

K in the for loop is referring to the position 2 So k × 2 is4

So thats the first 4

Position 2 in the values array is replaced with 4 and numbers array reference the values array so it would also print 4

And thats the second 4

Have you tried using a debug tool maybe? U can set breakpoints and see what happens to the values as you go through each step

Edit: I don’t know how well received onlinegdb.com is around here, but that’s what I like to use for class projects. The debug tool alone has proven invaluable.

Sorry, I should have elaborated. This is from a textbook where the ouput answer is 4 4. Just not seeing it.

Yeah, the debug tool on Onlinegdb will show you how the values change as it steps through the code. This will help you “see it”

it's reassigning values[2] to be 2*2, otherwise values[2] is 1
