Comparing strings:

String class contains the method which is used to compare two strings.

Some examples of string methods used for comparing strings are:

• “equals(s1)” - Returns true if the given string is equals to string “s1”.
• “compareTo(s1)” - Returns an integer greater than “0” if the string is greater, returns “0” if both the strings are equals and returns less than “0” if the given string less than s1.
• “contains(s1)” -Returns true if “s1” is a substring of the given string.
