Courses Plus Student 13,331 PointsI don't know why its asking me again to specify the array length to be 4 again
I have already done that and I don't know why it keeps asking. Error: arrayType[] variableName = new arrayType[arrayLength]
double[] lapTimes = new double {4};
lapTimes[0] = "2.2" ;

- when specifying an array length, the length should be enclosed in normal (square) brackets
- the language allows it, but the challenge doesn't like spaces between the type name and the bracket
- when setting a numeric value, don't put quotes around the number

Courses Plus Student 13,331 Pointsoh I think I made that mistake by accident I already knew that previously:
when specifying an array length, the length should be enclosed in normal (square) brackets
and I'm sure I did the other two though I still have this error : Bummer! Did you declare the 'lapTimes' variable as a 'double[]' or 'var'?
code: double[]lapTimes = new double[4]; lapTimes[0] = 2.2;
