<div dir="ltr" style="text-align: left;" trbidi="on"><b>Description:</b></p>
<p> This method has two variants which can be used to test if two string regions are equal.</p>
<p><b>Syntax:</b></p>
<p> Here is the syntax of this method:</p>
<pre class="highlight" name="code">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)
</pre>
<p>
<b>Parameters:</b></p>
<p> Here is the detail of parameters:</p>
<ul style="text-align: left;">
<li>toffset &#8212; the starting offset of the subregion in this string.</li>
<li>other &#8212; the string argument.</li>
<li>ooffset &#8212; the starting offset of the subregion in the string argument.</li>
<li>len &#8212; the number of characters to compare.</li>
<li>ignoreCase &#8212; if true, ignore case when comparing characters.</li>
</ul>
<p>
 <b>Return Value :</b></p>
<p></p>
<ul style="text-align: left;">
<li>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.</li>
</ul>
<p>
 <b>Example:</b></p>
<pre class="highlight" name="code">import java.io.*;

public class Test{
 public static void main(String args[]){
 String Str1 = new String("Welcome to 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));
 }
}
</pre>
<p>
This produces following result:</p>
<div style="background-color: #ff99cc;"><b>output:</b><br />
Return Value :false<br />
Return Value :false<br />
Return Value :false</div>
