This method has two variants which can be used to test if two string regions are equal.
Syntax:
Here is the syntax of this method:
public boolean regionMatches(int toffset, String other, int ooffset, int len) or public boolean regionMatches(boolean ignoreCase, int toffset, String other, int ooffset, int len)
Parameters:
Here is the detail of parameters:
- toffset — the starting offset of the subregion in this string.
- other — the string argument.
- ooffset — the starting offset of the subregion in the string argument.
- len — the number of characters to compare.
- ignoreCase — if true, ignore case when comparing characters.
Return Value :
- It returns true if the specified subregion of this string matches the specified subregion of the string argument; false otherwise. Whether the matching is exact or case insensitive depends on the ignoreCase argument.
Example:
import java.io.*; public class Test{ public static void main(String args[]){ String Str1 = new String("Welcome to www.dineshonjava.com"); String Str2 = new String("dineshon"); String Str3 = new String("DINESHON"); System.out.print("Return Value :" ); System.out.println(Str1.regionMatches(11, Str2, 0, 9)); System.out.print("Return Value :" ); System.out.println(Str1.regionMatches(11, Str3, 0, 9)); System.out.print("Return Value :" ); System.out.println(Str1.regionMatches(true, 11, Str3, 0, 9)); } }
This produces following result:
Return Value :false
Return Value :false
Return Value :false
hi i wana know what is the meaning of the region of the string is same
