Array Equality

The meaning of array equality

If we have two distinct arrays, what does it mean to say that the arrays are equal? Arrays are equal when their corresponding entries are equal. For example, the following two arrays are equal:

String[] names = {"alpha", "beta", "gamma", "delta"};
String[] tags = {"alpha", "beta", "gamma", "delta"};

The arrays have the same length, and the strings in corresponding elements are equal in value. That is, names[index] equals tags[index] as index ranges in value from 0 to 3. Since the arrays contain strings, we could test the equality of these entries by evaluating the Boolean expression ...
