How to test if an Array contains a value in Java using Linear Search ?

Question

Someone asked me this question and I dont have any answer, so thought to ask?

Answer 1

This method loop through array and use equals() method to search element. This actually performs a linear search over array in Java and return true if array has provided value.

public static <T> boolean contains(final T[] array, final T v) 
{
  for (final T e : array)
  {
     if (e == v || v != null && v.equals(e))
     {
        return true;
     }
  } 

  return false; 
}
