Method Detail

equals

public static <T> boolean equals(List<T> list1,
                 List<T> list2)

This method provides a convenient way to compare two Lists based on their content. Instead of using the List.equals(Object) method, a proper comparison is made by looking at the equivalence of each item. This equivalence is assessed by having the same item or by having Object.equals(Object) returning true. As we compare List s, the order of the items is checked too.

Notice that, as we are comparing items' equivalence (not strict equality), a List where two different items (a != b) are equivalent (a.equals(b) == true) is considered as equals to the same list where we swap these two items.

Parameters:

list1 -

list2 -

Returns:

true if both list have equals elements in the same order, false otherwise
