compareTo() function :- It is usaully used to compare strings.

Syntax : Str1.compareTo(Str2)

let be assume we have two String which is str1 & str2.

  • if str1>str2 then compareTo function will give positive value .
  • if str1 < str2 then compareTo function will give negative value .
  • if str1 is equal to str2 then compareTo function will give zero value.

In this below code , we have seen that compareTo function give positive value 👇👇

In this below code , we have seen that compareTo function give negative value.👇👇
