In this example, two integer arrays array1 and array2 are compared using Arrays.equals(). Since both arrays have identical elements in the same order, the method returns true. Example 2: Comparing Character Arr

Use for Nested Arrays: PreferArrays.deepEquals()overArrays.equals()when dealing with nested or multi-dimensional arrays to ensure a thorough comparison. Null Handling: The method handlesnullvalues gracefully. Twonullarrays are considered deeply equal, and anullarray is not equal to a non-null arra...
