str2.regionMatches(index: int, s1: String,s1Index: int, len: int): boolean

-
class region
{
public static void main(String[] arg)
{
String str1 = "Welcome to Smartprogrammeron.blogspot.in";
String str2 = new String("Welcome to SmartProgrammerOn.blogspot.in");
System.out.println("str1.regionMatches(offset of str1=10,str2,offset of str2=10,length=25) is " + str1.regionMatches(10,str2,10,25));
       System.out.println("str1.regionMatches(offset of str1=0,str2,offset of str2=0,length=10) is " + str1.regionMatches(0,str2,0,10));
}
}




It will match on given region of two strings.

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
