The different ways of comparing string in Java are as follows:
Using user-defined function
- if (string1 > string2) - it will return a positive value.
- if both the strings are equal lexicographically
i.e.(string1 == string2) it will return 0.
- if (string1 < string2) it will return a negative value.
The value is calculated as (int)str1.charAt(i) – (int)str2.charAt(i)
Using String.equals()
Using String.equalsIgnoreCase()
Using Objects.equals()
Using String.compareTo()
