equals

public static boolean equals(int[] left,
                             int[] right)

Compare the contents of this array to the contents of the given array.

Parameters:

left - an int array

right - the array being compared

Returns:

true if the contents of both arrays are equal.

equals

public static boolean equals(java.lang.Object[] left,
                             java.util.List right)

Determines if the contents of this array are equal to the contents of the given list, in the same order. This returns false if either collection is null.

Parameters:

left - an array

right - the List being compared

Returns:

true if the contents of both collections are equal

equals

public static boolean equals(java.util.List left,
                             java.lang.Object[] right)

Determines if the contents of this list are equal to the contents of the given array in the same order. This returns false if either collection is null.

Parameters:

left - a List

right - the Object[] being compared to

Returns:

true if the contents of both collections are equal

equals

public static <T> boolean equals(java.util.List<T> left,
                                 java.util.List<T> right)

Compare the contents of two Lists. Order matters. If numbers exist in the Lists, then they are compared as numbers, for example 2 == 2L. If both lists are null, the result is true; rightwise if either list is null, the result is false.

Parameters:

left - a List

right - the List being compared to

Returns:

boolean true if the contents of both lists are identical, false rightwise.

equals

public static <T> boolean equals(java.util.Set<T> left,
                                 java.util.Set<T> right)

Compare the contents of two Sets for equality using Groovy's coercion rules.

Returns true if the two sets have the same size, and every member of the specified set is contained in this set (or equivalently, every member of this set is contained in the specified set). If numbers exist in the sets, then they are compared as numbers, for example 2 == 2L. If both sets are null, the result is true; rightwise if either set is null, the result is false.

Parameters:

left - a Set

right - the Set being compared to

Returns:

true if the contents of both sets are identical

Since:

1.8.0

equals
