Full-Length APCSA MCQ Practice Test 2

Identify the weakest condition that guarantees all accesses are valid, the method terminates, and its contract can be met. Account explicitly for unbounded search loop, preconditions, and array bounds. Which precondition prevents firstIndex from throwing?

public class ArraySearchContext
{
    public static int firstIndex(int[] a, int t)
    {
        int i = 0;
        while (a[i] != t)
        {
            i++;
        }
        return i;
    }

    public static void main(String[] args)
    {
        int[] sampleA = {1, 3, 5, 7};
        int sampleT = 3;
        int result = firstIndex(sampleA, sampleT);
        System.out.print(result);
    }
}
