The two-argument function version is just a shortcut for theequals(d1, d2, 1)method call. In this case,d1andd2are considered equal if there are no floating point numbers between them. 5. Using Guava Google’sGuavais a big set of core Java libraries that extend the standard JDK capabi...
Step 4:In case of either line1 or line2 being null, assign false to areEqual and break the loop. Given, both of them aren't null, compare them using the equalsIgnoreCase() method. Continue the loop if equalsIgnoreCase() returns true, else break from the loop and assign false to areEqu...
