Java 9 — Array equals, compare, mismatch method
Mar 31, 2021
Traditionally Arrays are everywhere.
Some of the common problems with arrays in earlier java implementations was on how to compare them.
prior to Java 8
post Java 8
problem here was if we want to test a particular sequence /subset within the array we still had to loop through it.
so Java 9 onwards we have overloaded definition
Similarly we have the compare function definitions to compare any two arrays
There is a new function in Java9 mismatch which returns the first index from where mismatch occurs/length of sequence upto which two arrays match.
