Basic Array Access Strategy

Subject: Basic Array Access Strategy
From: Richard Patterson <email@hidden>

If I have an array of objects where each object has a set of instance variables, how do I ask the array to give me the first object in which one of the instance variables is equal to a certain value without knowing the values for the other variables?

In other words if I have tabular data in which one column is a wavelength and the other columns are red, green and blue sensitivities, is there a way I can find the sensitivities associated with a wavelength of 450 without sorting the array and walking through it on my own? Will I also be told if there is no entry at that wavelength?

Thanks.
