Java code that can compare in this way :<br /><br /><1 2 3 4> = <3 1 2 4><br /><1 2 3 4> != <3 4 1 1> <br /><br /><br />simple quadratic solution (which your original attempt is), is fine. In that case, you can do something like this:<br /><br />int count(SARAL SAXENAhttps://www.blogger.com/profile/01084233786047386880noreply@blogger.comtag:blogger.com,1999:blog-8712770457197348465.post-38238108955811189672013-01-02T18:48:24.208-08:002013-01-02T18:48:24.208-08:00I am looking for a way to compare Array elements t...I am looking for a way to compare Array elements to each other and find out How many elements or indexes are equals and How many elements are not equal? is there a way I can compare Array values in Java ?Anonymousnoreply@blogger.com
