#1. Java Program To Check Equality Of Two Arrays

We will write Java code to find if two one dimensional arrays are equal. For this problem, two arrays will be equal if:-
1. Lengths of both arrays are the same.
2. Both arrays contain the same element in the same order.
I have tried to explain the logic in such a way that will help you to crack interviews for SDET and Test Automation profiles.

public static boolean arrayCompare(int[] a, int[] b) {

if(a.length != b.length) return false;

Set<Integer> set = new HashSet<>();

for (int i = 0; i < a.length; i++) {
set.add(a[i]);
}
for (int j = 0; j < b.length; j++) {
if (set.add(b[j])) {
return false;
}

}
return true;
}

What if the order of numbers in arr2 is different... Then what's the approach?

[aniketkhandagale]

what if the arrays weren't sorted ? Did we assume here that the given arrays are sorted
