Matcher hasTransparentBounds() method in Java with Examples
The hasTransparentBounds() method of Matcher Class is used to check if this matcher has transparent bounds or not. By transparent bounds, it means that the matcher will be matched for the matching pattern beyond the region boundaries for getting a match, if the transparent bounds are set to true. This method returns a boolean value stating the same.
Syntax:
public boolean hasTransparentBounds()
Parameters: This method takes no parameters.
Return Value: This method returns a boolean value stating whether this matcher has transparent bounds or not
Below examples illustrate the Matcher.hasTransparentBounds() method:
Example 1:
import java.util.regex.*;
public class GFG {
public static void main(String[] args)
{
String regex = "(Geeks)" ;
Pattern pattern
= Pattern.compile(regex);
String stringToBeMatched
= "GeeksForGeeks Geeks for For Geeks Geek" ;
Matcher matcher
= pattern
.matcher(stringToBeMatched);
System.out.println( "Does this matcher"
+ " has transparent bounds: "
+ matcher
.hasTransparentBounds());
}
}
|
Output:
Does this matcher has transparent bounds: false
Example 2:
import java.util.regex.*;
public class GFG {
public static void main(String[] args)
{
String regex = "(F*F)" ;
Pattern pattern
= Pattern.compile(regex);
String stringToBeMatched
= "GFGFGFGFGFGFGFGFGFG FGF GFG GFG FGF" ;
Matcher matcher
= pattern
.matcher(stringToBeMatched);
matcher = matcher
.useTransparentBounds( true );
System.out.println( "Does this matcher"
+ " has transparent bounds: "
+ matcher
.hasTransparentBounds());
}
}
|
Output:
Does this matcher has transparent bounds: true
