Code: Select all
String[] numbers = new int[]{ "1", "2", "3", "4"}
String index = "2";
What would the following EL expression print?
The correct answer specified by ETSViewer: 3
How can it be "3", if this code will not compile?
1) int[] cannot be cast to String[]
2) no semi-colon after int[] array init;
P.S.: please, upgrade confirmation code generator! i have failed to correctly read it dosen times!

You are right new int should be replaced with new String. This has now been fixed.
thanks for your feedback!
BTW, if you signup on the forum, you will not be required to enter the code.
HTH,
Paul.

Hello,
just one point, we need a semicolon after : String[] numbers = new String[]{ "1", "2", "3", "4"} no?
or it will not compile

Yes, semicolon should be there. It will still not compile though because it is not the complete contents of the file

Hello Guys,
This question speaks that answer is 3, but I made a test and the results was 4.
Have anybody tested this question in compilation?
Please, Could anybody make the test too?
Code: Select all
String[] numbers = new String[]{ "1", "2", "3", "4"}; String index = "2"; What would the following EL expression print? ${numbers[numbers[index-1]]}
Best Regards,
Thiago

Hi,
The explanation says:
${numbers[numbers[index-1]]} resolves to ${numbers[numbers[1]]}, which resolves to ${numbers[2]}, which is 3.
Should it say:
${numbers[numbers[index-1]]} resolves to ${numbers[numbers[1]]}, which resolves to ${numbers["2"]}, which is 3.
as numbers[1] is the string 2?
