Is using a data structure really creates LOD violation?

Let's say, I have an array within the class C and methods M belongs to C calls this.



if(keys[i].equals(key)){



}


if we compare this scenario with the rules of the law, it is a violation. But in this case, isn't the keys[i] is actually still an element of the C. Is using a data structure ( array, list, vector ) makes a violation ( Because we only used them to put things together). And what is the solution to this? 



keys.atEqual(i,key)


something like that? And this is not implemented by the data structure, so how can one access and check the equality without the violation.

Full-time equivalent From Wikipedia, the free encyclopedia Jump to navigation Jump to search Full-time equivalent ( FTE ) or whole time equivalent ( WTE ) is a unit that indicates the workload of an employed person (or student) in a way that makes workloads or class loads comparable [1] across various contexts. FTE is often used to measure a worker's or student's involvement in a project, or to track cost reductions in an organization. An FTE of 1.0 is equivalent to a full-time worker or student, while an FTE of 0.5 signals half of a full work or school load. [2] Contents 1 U.S. Federal Government 2 In education 2.1 Example 3 Notes 4 References U.S. Federal Government [ edit ] In the U.S. Federal Government, FTE is defined by the Government Accountability Office (GAO) as the number of total hours worked divided by the maximum number of compensable hours in a full-time schedule as
