String Comparisons

The String class provides the methods for comparing strings, as given below:-

                      Method                                                            Defination

str2.equals(s1: String): boolean                        Returns true if this string is equal to string s1.

str2.equalsIgnoreCase(s1: String): boolean      Returns true if this string is equal to string s1 case                                                                                   insensitive.

str2.compareTo(s1: String): int                        Returns an integer greater than 0, equal to 0, or less                                                                                 than 0 to indicate whether this string is greater than,                                                                                 equal to, or less than s1.

str2.compareToIgnoreCase(s1: String): int      Same as compareTo except that the comparison is case                                                                           insensitive.

str2.regionMatches(index: int, s1: String,        Returns true if the specified subregion of this string       s1Index: int, len: int): boolean                         exactly matches the specified subregion in string s1.


str2.regionMatches(ignoreCase: boolean,       Same as the preceding method except that you can          index: int, s1: String,  s1Index: int,                specify whether the match is case sensitive.
 len: int): boolean

str2.startsWith(prefix: String): boolean         Returns true if this string starts with the specified prefix.

str2.endsWith(suffix: String): boolean           Returns true if this string ends with the specified suffix.
