Java - String regionMatches() Method


This method has two variants which can be used to test if two string regions are equal.


Here is the syntax of this method −

public boolean regionMatches(int toffset,
                             String other,
                             int ooffset,
                             int len)


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.

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.


public class Test {

   public static void main(String args[]) {
      String Str1 = new String("Welcome to");
      String Str2 = new String("Tutorials");
      String Str3 = new String("TUTORIALS");

      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));

This will produce the following result −


Return Value :true
Return Value :false
